The Future of Exchange Starts Here: Exchange Server 2010 SP1 Is Now Available

@Exchange Alright -- So I know its not "supported" but SP1 Beta folks do exist.  Since its not supported, its up to the community at large to do the work.  Of course I recommend taking backups of the store prior to any upgrade, especially this one.  That being said, I had no problem apply the update from SP1 Beta to SP1 RTM.  Store has mounted, I ran an integrity check, all is good.  All functions (mail flow, client access, OWA, etc) are testing fine.  Offline defrag and remounted, all good.  So for those who are running SP1 Beta, at first glance, the upgrade to SP1 RTM seems to be fairly easy and pain free.  Of course, your results may vary and again, backup backup backup, prior to starting it.
