- If you are running SMS 2003, its time to migrate. That product ended Mainstream support Jan 11, 2010
- If you are running the RTM version of Configuration Manager 2007, that level of product is now out of mainstream support as of July 2009
- If you are running Configuration Manager 2007 SP1, that level of product will go out of Mainstream support at the end of calendar 2010.
- If you are doing a net new deployment, the recommendation is ConfigMgr SP2, on Windows Server 2008 or ‘08 R2.
- If you are at a current level like SP2 now, its time to check out the very cool new features in the R3 beta – like Power Management.
