System Center Update Publisher (SCUP) 2011 supports Windows Server 2012
System Center Update Publisher 2011 now supports Windows Server 2012. The following are known issues:
Compatibility issue – WSUS 4.0 with WSUS 3.0 (with or without Service Packs):
Publishing to a server that runs Windows Server Update Services version 4.0 (WSUS 4.0), such as Windows Server 2012 should be performed from a server that runs Windows Server 2012 or a computer that runs Windows 8 and Remote Server Administration Tools. You cannot publish to a WSUS 4.0 server from a server that runs any version of WSUS 3.0 due to an incompatibility between WSUS 4.0 and WSUS 3.0, as it results in the error “WSUS version mismatch error”.
The WSUS administrator must be a member of the local administrators group of the System Center Update Publisher 2011 Server to use and publish updates to Windows Server 2012.
