Review this section carefully before you commence the upgrade process of the Central Manager.
Central Manager upgrade downtime window — How long the upgrade takes depends on the size of your deployment and the size of your database. The upgrade process of Central Manager itself may take an hour to complete.
Operating system upgrade downtime — The latest Central Manager 11.1 is supported on various Windows and Linux operating systems as mentioned in Central Manager and Manager system requirements.
If you want to upgrade the operating system of your Central Manager server, for example from Windows Server 2022 to Windows 2025, you must factor this in when you estimate the Central Manager downtime.
Database backup before and after upgrade — It is critical that you perform a full backup of your database using the All Tables as well as Config Tables options both before and after the upgrade. Backing up before upgrading enables you to roll back to the earlier version if you encounter any problem during the upgrade. Backing up immediately following the upgrade preserves your upgraded tables and provides a baseline of the 11.1 database that you upgraded to. Importantly, when you are backing up the database, there should not be any scheduled task running in the background.
Note
You cannot restore the database from a lower version of the Central Manager on a higher version of Central Manager.
