I currently have Exchange 2010 SP1 Rollup 6 and will be upgrading Server 2008 R2 with SP1.  I just wanted to make sure there are no special actions to take before I upgrade the Server to SP1.

Exchange 2010 SP1 is no longer supported, so you will need to upgrade that as well to at least SP2  - or , even better - SP3 .

Otherwise, upgrading the O/S to SP1 is fine.
