I need to move the SCCM 2007 R2 Database on SQL Server 2005 to SQL Server 2012 R2 DB. I am curious if the database will be compatible with the new SQL Server. I see there is an hotfix after the upgrade of 2012, http://support.microsoft.com/kb/2676776
. Is that necessary to do it before the upgrade or afterwards? Also is SCCM 2007 R2 compatible with ALWAYSON? I appreciate the help, will reward points as soon as an acceptable solution is available.
