There is a unique issue that blocks SCOM 2022 to SCOM 2025 upgrades.
If you have upgraded your Linux management packs at any time in SCOM 2022, you will likely be impacted. When this fails, it will leave your SCOM management server in an uninstalled state, and you will need to restore that management server from backup or VM snapshot to recover from this!
When the upgrade fails, if you open the log file, you might see the following errors:

This is caused by an updated Linux MP from SCOM 2023 UR3 (or later) that is newer and not upgrade compatible with the Microsoft.Unix.Library.mp that is included in SCOM 2025 RTM.
Please check your Microsoft.Unix.Library.mp (UNIX/Linux Core Library). If it is version 10.22.1330.0 or later, please open a support case with Microsoft and request a private hotfix for this issue. You will be supplied with 10.25.1005.1 version of Microsoft.Unix.Library.mp along with instructions on applying some updates to the SCOM management server and Gateway server roles.
Once you import/upgrade this MP, the SCOM upgrade can continue with success:
After the upgrade, follow the remainder of the instructions in the private hotfix to ensure you are in a supportable condition after the upgrade.
