This article is designed to describe how to batch upgrade Citrix Receiver to Citrix Workspace App with Single Sign-on and Desktop Lock.

---

Instructions

Receiver upgrades to the workspace app will automatically retain the Single Sign-on functionality previously set up, so bulk upgrades can be done as follows:
1. Create two folders, Programs and Scripts, on the file server or non-user resource server.
2. Share these two folders and assign Read access to Everyone: 3. Download the required Workspace App to the Programs folder from Citrix Workspace app 22.03.3000 for Windows, LTSR 2203.1 Cumulative Update 3 - Citrix (2203CU3 for reference only).
4. Download the required Desktop Lock to the Programs folder from Citrix Workspace app 2405 Desktop Lock - Citrix 
5. Create a new UpgradeReceiverToWorkspaceApp.bat file in the Scrips folder and type:

<share path>\CitrixWorkspaceApp.exe  /silent /noreboot
msiexec /i <share path>\CitrixWorkspaceDesktopLock.msi /qn /noreboot

6. Test the UpgradeReceiverToWorkspaceApp.bat file in the previous step on a single client and check if the program is successfully replaced in the control panel: 7. Open Group Policy Management and create a new Group Policy named UpgradeReceiverToWorkspaceApp in the OU where the client needs to be upgraded: 8. Edit the group policy and set the start up script (Computer Configuration -> Policies -> Windows Settings -> Scripts -> StartUp): 9. Batch reboot the client to trigger the group policy.

PS: Since it is a start up script, every time you boot or reboot, it will trigger the group policy (i.e. every time you boot or reboot, you will reinstall Workspace and Desktop Lock), so it is recommended that you delete the group policy after the batch upgrade is completed.
