SCOM R2 to OM12 upgrade: A caveat when upgrading SQL 2005 to SQL 2008 R2 SP1

When one has a SCOM R2 environment in place based on SQL Server 2005 and want to upgrade to OM12, it’s required to upgrade to SQL Server 2008 R2 SP1 first.

Even though I have posted a whole series of articles about that upgrade process, there is one small but important detail to reckon with. Otherwise OM12 will generate errors in the OpsMgr event log of the OM12 Management Servers.

It’s all about the OpsMgr and OpsMgrDW databases which still run in the SQL 2005 compatibility mode. OM12 doesn’t like that and will throw errors in the OpsMgr event log.

KB2700028 tells you how to solve it.
