- If you got an Exchange 2010 DAG, and want to properly update the DAG members, check the instructions here.
Note that Cumulative Updates can be installed directly, i.e. no need to install RTM prior to installing Cumulative Updates. Note that once installed, you can’t uninstall a Cumulative Update nor any of the installed Exchange server roles. The order of upgrading Exchange 2013 servers is irrelevant, unlike with previous generations of Exchange. Exchange 2010 Rollups are cumulative per service pack level, i.e. they contain fixes released in earlier updates.
