After applying a cumulative update\ service pack on SharePoint 2007 Servers when we run PSConfig wizard which fails on step 8 of 9 or psconfig.exe -cmd upgrade -inplace b2b –wait -force it fails on step 3 with the error message

From Upgrade Log:

[SharedServiceDatabaseSequence] [DEBUG] [10/9/2012 4:11:06 PM]: Calling get SchemaVersion on Database SharedServices1_SSPDB, Status = Upgrading.

[SharedServiceDatabaseSequence] [ERROR] [10/9/2012 4:11:06 PM]: Upgrade object too new (build version = 12.0.6612.1000, schema version = 12.0.1.0). Current server (build version = 12.0.6425.1000, schema version = 12.0.1.0).

Resolution:

Now from the above error: Current server (build version = 12.0.6425.1000, schema version = 12.0.1.0) indicates the current server built, whereas Upgrade object too new (build version = 12.0.6612.1000, schema version = 12.0.1.0) is what is expected.

On the SharePoint Server where the upgrade is failing with above error message

Click on Start –> Run –> Type “Regedit” and then navigate to following node.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0

Double click on BuildVersion and then update it from 12.0.6425.1000 to 12.0.6612.1000

Now, run the PSConfig wizard or psconfig.exe -cmd upgrade -inplace b2b –wait -force and it should succeed.
