Description

Important: After you receive an extension 

An extension is provided as a one-time-only exception to allow continued use of file-based licensing for a limited period. Customers must migrate to License Activation Service (LAS) before the extension expiration date to avoid service disruption. 

  • Important caveat (Citrix License Server): If a customer has applied the extension file to a License Server version that does not support LAS (pre-LAS supported), it is necessary to upgrade to a LAS-supported License Server version. Upon completion of the upgrade, the extension files may be overwritten, requiring the customer to reapply the extension files. To mitigate the risk of unexpected downtime, it is recommended to schedule a maintenance window and back up the extension files prior to upgrading. After the License Server upgrade, restore or reapply the extension files as appropriate. 

 

Step 1: Setting up / Review your Citrix Cloud account 

To activate and use the License Activation Service (LAS), you need a Citrix Cloud account. Having a Citrix Cloud account also allows you to temporarily suspend LAS enforcement to download extension files. All Citrix customers with current entitlements can create Citrix Cloud accounts. For instructions on setting up an account, visit https://docs.citrix.com/en-us/citrix-cloud/overview/signing-up-for-citrix-cloud/account-management#create-a-citrix-cloud-account.  

 

IMPORTANT: Citrix Cloud deployments in Japan (JP) and Government (CCG) do NOT support the one-time extension. Ensure that a cloud account in US, EU OR AP-S control planes. Customers can create new cloud accounts in different control planes as needed. 

Step 2: Downloading License Files from MyAccount 

As part of the one-time extension, new license files will be made available in the Citrix → MyAccount (https://www.citrix.com/account). Existing administrators should already be familiar with the process of downloading license files. More information can be found in the product documentation: https://docs.citrix.com/en-us/licensing/current-release/manage-licenses-myaccount.html#to-access-manage-licenses-on-citrixcom. 

IMPORTANT: To get new expiration dates, administrators need to return and allocate licenses. Redownloading licenses files will not refresh the expiration dates.

Citrix License Server

There are two supported methods to apply the license file extension blob:

Option 1: Use the Automated Tool (Recommended)

Citrix provides a supported utility that automates the application of the license file extension blob. This method is documented in CTX696542.

Using the tool is the recommended approach, as it reduces the risk of errors and ensures consistent application of the license file extension.

Refer to CTX696542 for detailed instructions on downloading and using the tool.

 

Option 2: Apply the License File Extension Blob Manually

Alternatively, the license file extension blob can be applied manually by following the following steps.

1. (Optional step) Go to license server and check the current deadline)

2. Go to License Server and Backup the existing "legacylicenseextension.blob" -file present in C:\Program Files (x86)\Citrix\licensing\MyFiles

Note: This is the default License server installed directory, if you have installed the license server at a custom directory, follow the custom directory path.

3. Unzip the license file extension blob and place the extracted “legacylicenseextension.blob” at C:\Program Files (x86)\Citrix\licensing\MyFiles\

4. If customers current license files have 15th April 2026 as the expiry date, they can download the latest license files from Citrix MyAccount which will have updated expiry date according to the end date of the exception approval. Upload those license files to License server. Verify the new dates in the studio.

5. Restart the “Citrix Licensing” service

(Optional step) Validate the extension date:

To validate the extension: (This can be done before and after placing the blob to see the current deadline and revised deadline)

6. Open the log file present at the location C:\Program Files (x86)\Citrix\Licensing\LS\Logs\log_vdxudlic.log

7. Find the last instance of following lines at the end of the file:(these lines could be present multiple times)

a. Parsed CutOffTime := <timestamp> from output

b. Cutoff timestamp <timestamp> not reached, no need to perform inventory and checkout

8. The <timestamp> is in epoch seconds. Use the following tool to convert it to actual date and time: https://www.epochconverter.com. The new date will match with the approved exception end date.

9. Verify the new entitlement end date in Studio.

Note:

1. If the customer is on non-LAS supported license server and has applied the extension file, it is necessary to upgrade to a LAS-supported License Server version. Upon completion of the upgrade, the extension files may be overwritten, requiring the customer to reapply the extension files. To mitigate the risk of unexpected downtime, it is recommended to schedule a maintenance window and back up the extension files prior to upgrading. After the License Server upgrades, restore or reapply the extension files as appropriate.

2. LS version 51000 does not log the Cutoff timestamp, and it's recommended to be on LS 53100 and above to verify the updated cutoff timestamp after applying the extension blob.

 

 

 

Step 3b: NetScaler deployments  

Please follow the below steps if the license file extension is meant to be for NetScaler or Console. 
 

  1. Login to Citrix cloud and go to Licensing -> Licensed deployment -> license file extension and click Generate extension file. 
    Note: This option is available for the customers who have got the exception approved, and they are enabled in the backend. This option will be available only till the end date of the exception which can be seen on the screen “License file extension is valid until <Date>”

- To know the Host ID of your NetScaler Console on-prem, you can navigate to NetScaler Console on-prem GUI > License

image.png

- To know the Host ID of your NetScaler ADC, you can use the below mentioned CLI command. 
Note: Do not use the NetScaler ADC Host ID mentioned on NetScaler ADC GUI, use the CLI given Host ID only. 
Note: If you have already used the NetScaler GUI-based Host ID, regenerate the LAS exception file extension blob using the Host ID from the NetScaler CLI command output and re-perform all the steps. 

 

CLI command: shell /netscaler/lmutil hostid -n 
 
Sample command and output: 
> shell /netscaler/lmutil hostid -n 
5aaa23b97486 
Done 
> 

 

- To know the Host ID of your NetScaler SVM, you can navigate to NetScaler SVM GUI > Configuration tab and note the Host ID shown there.

Click “Download” to download the license file extension blob. 

 

 
Prerequisites and Points to Note:  

  • You have referred to the above-mentioned section of the document which explains how to download the LAS exception blob (file extension blob) and have also downloaded the file-based license file(s) with extended expiry date from My Citrix (based on the approved exception date): 
  • Note: If you are a customer who has downloaded and applied File based license files on/after Sept 2025, then you would have license expiry date as 15 April 2026. In that case, you need to download and apply the LAS exception blob and download from Citrix → MyAccount and apply the file-based licenses with extended expiry date.  
  • Ensure that you have unzipped the downloaded exception zip file and are using the extension file blob which is inside it.  
  • You have a non-expired license with valid SA date and valid license expiry date.  
  • Please ensure that you are referring to the correct section below for application of the LAS exception license file extension blob as well as updated license files. 
  • For NetScaler local licenses (Eg: NetScaler Fixed Capacity Subscription License type and NetScaler Perpetual License Type) - the extension blob as well as the updated license files need to be applied on the NetScaler (ADC, SVM). Please refer to section “NetScaler (ADC, SVM)" for more details. 
  • For Console based license type (Eg: CPL/UHMC/Pooled Bandwidth/Pooled vCPU License Type) - the extension blob as well as the updated license files need to be applied on the Console on-prem or Console Service, whichever is acting as the license server. Please refer to Console on-prem or Console Service section (depending on which is the license server) for more details. 
    Note: The updated Zcap SW license files in this case need to be directly applied to the NetScaler MPX or SDX instance. 
     

 

NetScaler (ADC, SVM) 
 

Note: Applies to NetScaler local license type: Fixed Capacity Subscription License type and NetScaler Perpetual License Type. 
 
Important Note: 

If you are using or planning to use LAS exception blobs of type file extension on SVM 13.1 60.x or later, with NetScaler local license types (e.g., Fixed Capacity Subscription or perpetual licenses), please note the following: 

A critical issue (JIRA ID: NSSVM-7346) will cause SDX to become non-functional, and the LAS exception file extension will not be honored. 

To resolve this: 

  • Upgrade to SVM releases with the fix: 13.1 62.27 or 13.1 61.28 or 13.1 60.33  
  • Refer to this documentation (section titled ‘NetScaler deployments’ onwards) and follow all the steps in the documentation if you have not already completed the steps on an earlier version. 

 

Steps: 
Refer to all 4 steps 
 

Step 1: How to use the LAS exception license file extension blob: 
 
- For ADC:  
Create a folder named 'extension' in the path /nsconfig/license 
Run the command “chmod 775 /nsconfig/license/extension“. This gives appropriate permissions to the folder.   
Then upload this LAS exception blob (to continue running file based license) to path /nsconfig/license/extension. 
Note: If the NetScaler instance is already unlicensed, then a reboot will also be required. 
Note: By default, it takes upto 24 hours for the applied LAS exception blob to come into effect and be honored. If you need it to come into effect and be honored immediately, then NetScaler ADC reboot will be required. 
 
- For SVM:  
Create a folder named 'extension' in the path /mpsconfig/license 
Run the command “chmod 775 /mpsconfig/license/extension“. This gives appropriate permissions to the folder.   
Then upload this LAS exception blob (to continue running file based license) to path /mpsconfig/license/extension. 
Note: If the NetScaler instance is already unlicensed, then a reboot will also be required. 
Note: By default, it takes up to six hours for the applied LAS exception blob to come into effect and be honored. If you need it to come into effect and be honored immediately, then NetScaler SVM reboot will be required. 

 

Step 2: How to use the latest file-based license file 
 
Follow this documentation to install and apply the latest license file:  

 

Step 3: How to verify if the LAS exception license file extension blob has been applied properly on NetScaler ADC, SVM 
 
Important Note: We recommend using approach (3b) 'Verification using logs’ approach or (3c) ‘Verification using script’ approach since they are deterministic ways of verification. The (3a) ‘Verification using GUI banner’ approach is not deterministic and may not give reliable output in all scenarios.  
 
3a. Verification using NetScaler ADC GUI banner or NetScaler SVM GUI banner 
 
There is a warning banner on the NetScaler ADC, SVM product GUI that keeps coming up if customer is on LAS compatible/enforced builds and yet using file-based licensing. This warning banner starts 120 days before 15th April 2026 (LAS enforcement date) and shows up each time admin logs in. 

Once the LAS exception blob is applied, this warning banner will go away.  

This is what the NetScaler ADC, SVM product GUI warning banner text says: Please transition to LAS (License Activation Service) based licensing from file-based licensing to avoid any service disruption, please refer to product documentation for more details. 


Sample Screenshot: 

image.png

Note: This GUI warning banner starts 120 days before the LAS enforcement / cut-off date. If you have got a LAS exception (file extension) for 3 months with end date of 15th July 2026, then your cut-off date is extended to 15th July 2026, and this banner will again start appearing from 120 days before the new cut-off date - i.e. you will again start seeing it from 15th March 2026. 
 
3b. Verification using NetScaler ADC or NetScaler SVM logs 

Note: This GUI warning banner starts 120 days before the LAS enforcement / cut-off date. If you have got a LAS exception (file extension) for 3 months with end date of 15th July 2026, then your cut-off date is extended to 15th July 2026, and this banner will again start appearing from 120 days before the new cut-off date - i.e. you will again start seeing it from 15th March 2026. 
 
3b. Verification using NetScaler ADC or NetScaler SVM logs 

For NetScaler SVM: 

(i) Login to SVM using nsrecover username and password. Note that the password for nsrecover is the same as that of nsroot. 

(ii) Run the command: zgrep -nri get_lmgrd_extension_remaining /var/mps/log/mps_inventory.log* 

Sample output (i.e. the log line to look for): 2 Apr 26 10:26:46.430 +0000 [Debug] [#1] get_lmgrd_extension_remaining: File 'legacyext.blob' host: 112233445566, expiry: 1782863969 

(iii) The 'expiry' is a EPOCH timestamp which can be converted into a regular date and time using any opensource tool. 

Example: EPOCH convertor tool (Link: https://www.epochconverter.com/). Use the expiry value '1782863969' which is in EPOCH timestamp and convert it to regular date and time. 

(iv) The date and time seen here should be aligned with the approved LAS exception file extension expiry date.

For NetScaler ADC: 

(i) Login to ADC using nsrecover username and password. Note that the password for nsrecover is the same as that of nsroot. 

(ii) Run the command: zgrep -nri nscfe_update_lasenforcement_extension /var/log/ns.log* 

Sample output (i.e. the log line to look for): Mar 25 16:16:34 <local0.info> ns nsnetsvc[814]: nscfe_update_lasenforcement_extension(): LAS enforcement extended timestamp 1780876769 

(iii) The 'LAS enforcement extended timestamp' is an EPOCH timestamp which can be converted into a regular date and time using any open-source tool. 

Example: EPOCH convertor tool (Link: https://www.epochconverter.com/). Use the LAS enforcement extended timestamp value '1780876769' which is in EPOCH timestamp and convert it to regular date and time. 

(iv) The date and time seen here should be aligned with the approved LAS exception file extension expiry date.

3c. Verification using script on NetScaler ADC or NetScaler SVM 
 
The script automates the log-based verification for the NetScaler ADC or SVM. 
 
Steps for NetScaler ADC: 
 
Script Link - Script for LAS exception license file extension blob validation 
(If the above link doesn't work for you, please use this KB article link to get the script -  
https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX696544&articleTitle=Script_for_LAS_exception_license_file_extension_blob_validation&) 

  1. Copy the script (via SCP) to /var/ directory on NetScaler ADC
  2. Login to CLI (via SSH) to NS ADC and enter shell prompt
  3. Go to var directory: cd /var/
  4. Execute the script using this command: python extension_check.py 
     
    Sample Output for NetScaler ADC:  
     
    ================================================ 
    Log file analysis 
    LAS Exception for file extension Applied: YES 
    LAS Exception for file extension UTC end date: 2026-06-30 23:59:29 
    ================================================ 
    ================================================ 
    Blob file analysis 
    LAS Exception for file extension Applied: YES 
    LAS Exception for file extension UTC end date: 2026-06-30 23:59:29 
    ================================================ 

 

  • If you are seeing both the outputs with a "YES" and with the accurate file extension date, then verification is successfully completed. If not, the exception file extension blob has not been applied properly. 
  • If you see a "YES" in the blob file analysis and a "NO" in the log file analysis, it means that the blob copied is applicable for this NetScaler ADC however it has not yet been read by the NetScaler ADC. By default, it takes upto 24 hours for the applied LAS exception blob to come into effect and be honored. If you need it to come into effect and be honored immediately, then NetScaler ADC reboot will be required. Try the script once again after this interval is over or the reboot has been done. 
     
     

Steps for NetScaler SVM: 
 
Script Link - Script for LAS exception license file extension blob validation 
(If the above link doesn't work for you, please use this KB article link to get the script -  
https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX696544&articleTitle=Script_for_LAS_exception_license_file_extension_blob_validation&) 
 
1. Copy the script (via SCP) to /var/ directory on NetScaler SVM 
2. Login to CLI (via SSH) to NS SVM and enter shell prompt 
3. Go to var directory: cd /var/ 
4. Execute the script using this command: python extension_check.py 

 
Sample Output for NetScaler SVM: 
================================================ 
Log file analysis 
LAS Exception for file extension Applied: YES 
LAS Exception for file extension UTC end date: 2026-06-30 23:59:29 
================================================ 
================================================ 
Blob file analysis 
LAS Exception for file extension Applied: YES 
LAS Exception for file extension UTC end date: 2026-06-30 23:59:29 
================================================ 
 

  • If you see BOTH the outputs with a "YES" and with the accurate file extension date, then verification is successfully completed. If not, the exception file extension blob has not been applied properly. 
  • If you see a "YES" in the blob file analysis and a "NO" in the log file analysis, it means that the blob copied is applicable for this NetScaler SVM however it has not yet been read by the NetScaler SVM. By default, it takes upto 6 hours for the applied LAS exception blob to come into effect and be honored. If you need it to come into effect and be honored immediately, then NetScaler SVM reboot will be required. Try the script once again after this interval is over or the reboot has been done. 

 

 

Step 4: Additional steps to take if the NetScaler is unlicensed (specific to the NetScaler form factor): 
 

For NetScaler ADC:  
 

VPX (non-SDX), BLX:  
Warm reboot (if not already done as mentioned in step 1 and step 2) 
CLI command: reboot –warm 
 

MPX: 

  • Warm reboot the MPX (if not already done as mentioned in step 1 and step 2) 
    CLI command: reboot -warm 
  • Pick up the ns.conf (from /nsconfig directory) from the time when NS was licensed (typical file name format ns.conf.(0-9) 
  • Replace current ns.conf with the old ns.conf found in previous step 
  • Warm reboot the MPX 
    CLI command: reboot –warm 
     

CPX: Not Applicable. Reason: CPX does not support NetScaler local licenses 

 For NetScaler SVM:  

 

 

NetScaler Console Service 

 
Note: Applies to Console based licenses: CPL/UHMC/Pooled Bandwidth License Type 
 
Steps: 
Refer to all 4 steps 

Step 1: How to use the LAS exception license file extension blob: 
Go to Console Service GUI: NetScaler Licensing > License Management > Manual License Files Management > License Files section, select "Upload License Files from a local computer" and click on "Browse". Upload the LAS exception blob and then apply it.

Reboot all the external agents. For this, login to each external agent via SSH using username nsrecover and <password> and on the external agent CLI execute the command 'shutdown -r now'.

Step 2: How to use the latest file-based license file 
Follow this documentation to install and apply the latest license file(s): 

https://docs.netscaler.com/en-us/netscaler-console-service/manage-licenses/license-management#manually-managed-entitlements-file-based-licenses 

 

Step 3: How to verify if the LAS exception license file extension blob has been applied properly on NetScaler Console Service

Verification using Console Service > NetScaler Licensing > License Management GUI  

For customers who have applied the LAS exception license file extension blob on Console Service, the Console Service > NetScaler Licensing > License Management GUI showcases a notification displaying the confirmation that the file extension blob has been applied and showcases the validity of the extension blob.  

Example: “LAS exception of type License file extension is applied and valid until <(Day) (date) (time) (time-zone of the Console GUI)>”  
If you see this notification, then you have verified that the license file extension blob has been applied. If you do not see this notification, then the license file extension blob has not been applied.  
Screenshot: 

image.png

Step 4: Additional steps to take if the NetScaler is unlicensed (specific to the NetScaler form factor): 
 
Once the license information is visible in Flexed/ Pooled license dashboard under ‘Manually managed entitlements’ tab, individual NetScaler/SVM instances can be licensed. 
 
For NetScaler:   

VPX (non-SDX), BLX:  

License using this documentation reference (this section link and onwards):  
https://docs.netscaler.com/en-us/netscaler-console-service/manage-licenses/configure-flexed-licensing#manually-managed-entitlements-file-based-licensing  

 

MPX:  

Confirm that valid Z-cap license files are on the device. If not, upload/apply them. License using this documentation reference (this section link and onwards): https://docs.netscaler.com/en-us/netscaler-console-service/manage-licenses/configure-flexed-licensing#manually-managed-entitlements-file-based-licensing 

Restore ns.conf after performing previous step. 

Pick up the ns.conf (from /nsconfig directory) when NS was licensed (typical file name format ns.conf.(0-9)    

Replace current ns.conf with the old ns.conf found in previous step.    

Warm reboot MPX 
CLI command: reboot –warm 
 

CPX: No additional action needed. 
 

SDX (SVM): 

 

NetScaler Console on-premises

Note: Applies to Console based licenses: CPL/UHMC/Pooled Bandwidth License Type

Important Note:

If you are using or planning to use LAS exception blobs of type file extension on Console on-prem version 13.1 60.x or later, with Console-based license types (e.g., CPL, UHMC, Pooled BW), please note the following:

A critical issue (JIRA ID: NSADM-127861) will cause the Console on-prem to become non-functional, and the LAS exception file extension will not be honored.

To resolve this:

  • Upgrade to Console on-prem releases with the fix: 13.1 62.27 or 13.1 61.28 or 13.1 60.33
  • Refer to this documentation (section titled ‘NetScaler deployments’ onwards) and follow all the steps in the documentation if you have not already completed the steps on an earlier version.

 

Steps:
Refer to all 4 steps

Step 1: How to use the LAS exception license file extension blob:
Create a folder named 'extension' in the path /mpsconfig/license
Run the command “chmod 775 /mpsconfig/license/extension“. This gives appropriate permissions to the folder.
Then upload this LAS exception blob (to continue running file-based license) to path /mpsconfig/license/extension.
Note: If the NetScaler Console managed NS instances are already in grace or unlicensed, then a reboot of Console will also be required.

Note: By default, it takes upto six hours for the applied LAS exception blob to come into effect and be honored. If you need it to come into effect and be honored immediately, then Console on-prem reboot will be required.

Note: For Console on-prem HA, apply the same extension blob on both the nodes. Do not generate the extension blob individually for both nodes. Generate it for the primary node and apply on both primary and secondary node.

 

Step 2: How to use the latest file-based license file
Follow this documentation to install and apply the latest license file(s):
https://docs.netscaler.com/en-us/netscaler-application-delivery-management-software/current-release/license-server/license-management#manually-managed-entitlements-file-based-licenses 

Step 3: How to verify if the LAS exception file extension blob has been applied properly on NetScaler Console on-prem

Important Note: We recommend using approach (3b) 'Verification using logs’ approach or (3c) ‘Verification using script’ approach since they are deterministic ways of verification. The (3a) ‘Verification using GUI banner’ approach is not deterministic and may not give reliable output in all scenarios.

 Verification using Console on-prem GUI banner

There is a warning banner on the NetScaler Console on-prem product GUI that keeps coming up if customer is on LAS compatible/enforced builds and yet using file-based licensing. This warning banner starts 120 days before 15th April 2026 (LAS enforcement date) and shows up each time admin logs in.

Once the LAS exception blob is applied, this warning banner will go away.

This is what the NetScaler Console on-prem product GUI warning banner text says: Please transition to LAS (License Activation Service) based licensing from file-based licensing to avoid any service disruption, please refer to product documentation for more details. Sample Screenshot:

image.png

Note: This GUI warning banner starts 120 days before the LAS enforcement / cut-off date. If you have got an LAS exception (file extension) for 3 months with end date of 15th July 2026, then your cut-off date is extended to 15th July 2026, and this banner will again start appearing from 120 days before the new cut-off date - i.e. you will again start seeing it from 15th March 2026.

  

3b. Verification using Console on-prem logs

(i) Login to Console on-prem using nsrecover username and password. Note that the password for nsrecover is the same as that of nsroot.

(ii) Run the command: zgrep -nri get_lmgrd_extension_remaining /var/mps/log/mps_inventory.log*

Sample output (i.e. the log line to look for): 2 Apr 26 10:26:46.430 +0000 [Debug] [#1] get_lmgrd_extension_remaining: File 'legacyext.blob' host: 112233445566, expiry: 1782863969

(iii) The 'expiry' is a EPOCH timestamp which can be converted into a regular date and time using any opensource tool.

Example: EPOCH convertor tool (Link: https://www.epochconverter.com). Use the expiry value '1782863969' which is in EPOCH timestamp and convert it to regular date and time.

(iv) The date and time seen here should be aligned with the approved LAS exception file extension expiry date.

3c. Verification using script on NetScaler Console on-prem

The script automates the log-based verification for the NetScaler Console on-prem.

Steps for NetScaler Console on-prem:

Script Link - Script for LAS exception license file extension blob validation
(If the above link doesn't work for you, please use this KB article link to get the script -
https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX696544&articleTitle=Script_for_LAS_exception_license_file_extension_blob_validation&)

 1. Copy the script (via SCP) to /var/ directory on NetScaler Console on-prem
 2. Login to CLI (via SSH) to NetScaler Console on-prem and enter shell prompt
 3. Go to var directory: cd /var/
 4. Execute the script using this command: python extension_check.py

Sample Output:
================================================
Log file analysis
LAS Exception for file extension Applied: YES
LAS Exception for file extension UTC end date: 2026-06-30 23:59:29
================================================
================================================
Blob file analysis
LAS Exception for file extension Applied: YES
LAS Exception for file extension UTC end date: 2026-06-30 23:59:29
================================================

  • If you see BOTH the outputs with a "YES" and with the accurate file extension date, then verification is successfully completed. If not, the exception file extension blob has not been applied properly.
  • If you see a "YES" in the blob file analysis and a "NO" in the log file analysis, it means that the blob copied is applicable for this NetScaler Console on-prem however it has not yet been read by the NetScaler Console on-prem. By default, it takes upto 6 hours for the applied LAS exception blob to come into effect and be honored.
