ConfigMgr 2012 R2 – Replication Issues after upgrading CAS
Microsoft has just released more information and a resolution for a problem scenario in an SP1 CU2 or CU3 environment where child primary sites were entering maintenance mode after the Central Administration Site (CAS) had been upgraded to Configuration Manager 2012 R2.
- This issue has been resolved for all new System Center 2012 R2 Configuration Manager upgrades as of November 14, 2013. New installations or upgrades will download updated setup prerequisite files.
- Customers that are working with site servers not connected directly to the Internet should use the Configuration Manager Setup Downloader.
- Existing hierarchies that have already upgraded the central administration site but cannot upgrade child primary site(s) can be repaired by running a SQL script against the site database at the child primary site(s).
More details about the issue and the SQL script to fix existing hierarchies can be found here.
