While upgrading to version 24.3.9, customers may receive the following error message:

“The Management Service must be at revision 24.6.0.0 before it can be upgraded to version 25.3.0.1008. Please manually upgrade to the latest 2403 release.”

This error occurs due to the selection of an upgrade disk for a newer version (e.g., 2503 or 2409) during the "Browse for Upgrade Disk" process, which causes the system to expect a higher revision number than required for version 24.3.9.

Ensure to back up your system before performing any upgrade to avoid potential data loss.

The error occurs because a newer upgrade disk (such as for version 2503 or 2409) was selected, which caused the system to expect a different revision number than required for version 24.3.9.

To resolve the issue and successfully upgrade to 24.3.9, follow these steps:

• Step 1: Access the file location on the ELM : /usr/local/UnideskUpgrader/thisbuild.txt

• Step 2: Edit the contents of the thisbuild.txt file.

• Step 3: Set the contents of the file to 2403.0.0.0.

• Step 6: Ensure that only the disk for version 24.3.9 is selected for the upgrade.

Following these steps will allow the upgrade to version 24.3.9 to proceed without the error.
