The existing database is not compatible with this version of WSUS

Today I wanted to re-install WSUS again in a production environment where ConfigMgr 2012 was also on place.

Normally these steps are followed:

1) Uninstall WSUS (without database, logfiles, updates)
2) Install WSUS again + KB2720211 + KB2734608 updates
3) Reboot the server (you never know)
4) Start "Synchronize Software Updates"

This time I couldn't connect to the WSUS database anymore. Error message: "The existing database is not compatible with this version of Windows Server Update Services 3.0 SP2. Select another database instance or create a new database"


Looking on the existing WSUS Database I found out that permissions were not correct. After adding the Installation account to the WSUS database with Sysadmin permissions it was working again.

Hope it helps!

    Hi there. How did you add the installation account to the WSUS database? I suspect a permissions problem too as I have the same error message.

      Hi, just set permissions with the Installation account used during WSUS installation. This can be done in SQL Server Management Studio. The account must have Sysadmin permissions on the WSUS database. Hope it helps!
