Upgrading Server 2008 R2 ConfigMgr Sites

Author by Matt Herman

The release of branch 1602 for System Center Configuratoin Manager (ConfigMgr) brings support for upgrading Site Servers from Windows Server 2008 R2 to Windows Server 2012 R2.  This is important for many organizations becuase support for ConfigMgr Sites running on Server 2008 R2 will end in early 2017.  In the video below, I walk through the process of upgrading the OS and verifying ConfigMgr is running properly.
