ReDownload Updated SCCM Setup Prerequisite Files to Fix a Known Issue Configuration Manager MEMCM. Another known issue added to my list of 7 SCCM ConfigMgr 2012 R2 Known Issues. Several customers reported to Microsoft that child primary sites were entering maintenance mode after upgrading the CAS from SCCM ConfigMgr to SCCM.
I didn’t face this issue probably because I don’t use PULL DPs in my Dev environment.
ReDownload Updated SCCM Setup Prerequisite Files to Fix a Known Issue Configuration Manager MEMCM
As per the Technet blog here, we can resolve the REPLICATION ISSUE between CAS and Primary servers by re-downloading the prerequisites files of SCCM.
Microsoft had updated the prerequisite files of SCCM 2012 R2 on 14th Nov 2013. So if you’ve downloaded the prerequisite files before 14th Nov then go ahead and download them again.
Especially, when you’ve PULL DPs in your environment. More details about this issue http://blogs.technet.com/b/configmgrteam/archive/2013/11/26/replication-errors-in-system-center-2012-r2-configuration-manager.aspx
