Upgrading the OS / LifeKeeper (OS Patching)

Best Practices for Handling Operating System Upgrades with LifeKeeper

!Rolling upgrades are NOT supported when upgrading your operating system (e.g., from Windows Server 2016 to Windows Server 2022). Attempting a rolling upgrade without proper preparation can lead to system instability and unexpected behavior.

To ensure a smooth transition, you must remove LifeKeeper/DataKeeper from your Windows Server platform before performing the upgrade to a newer Windows Operating System

Refer to our detailed instructions in the “Removing/Uninstalling LifeKeeper” section for guidance on this process.

*Note: After completing the operating system upgrade and reboot, make sure to manually delete the C:\LK and C:\Program Files (x86)\SIOS\DataKeeper directories to avoid conflicts during reinstallation or future use.

By adhering to these steps, you can avoid potential issues and maintain the integrity of your environment.
