I have SEPM 12.1.4 running on Windows Server 2003 in my environment at Primary site. The SEPM is using MS SQL Server 2008 database that is running on separate machine.
This is 3500+ users SEP environment. I also have two SEPMs running in DR site as backup. Clients are configured to fall back to DR site's SEPMs in case primary SEPM goes down. DR site's SEPMs also use MS SQL Database that is running on separate machine in DR site.
Replication is also configured between SEPM at Primary site with one of SEPM at DR site.
We are decomissioning these old SEPM server running Windows Server 2003 and moving to new Physical servers that are running Windows Server 2012. Important point is that these will be all new Windows Server 2012 installations not migrated/updated ones.
What should i do for successfully migrating all three SEPM 12.1.4 on old servers to 12.1.6 on new Windows Server 2012 servers? Detailed steps will be much appreciated. Thanks.
