Released: Exchange Server 2013 RTM Cumulative Update 1

Nino Bilic:  I completely agree and understand why Microsoft abandoned In-place version upgrades, it has always made a lot of sense to move to new gear when you upgrade the messaging system.  I've been working with Microsoft messaging products since Courier days and there were times when the upgrade in place worked and then after a while it didn't make any sense.  HOWEVER, this new "All In" update process might equates to an In-Place ugprade, which is mystifying.  There is no way to roll back, it either works or it doesn't work.  The number of issues with CU1 are incredible and you've left customers with no easy way to roll back.  It is illogical and off the mark.  Worse, right now there doesn't seem to be any acknowlegement of these issues and "we're on it" and "we'll keep you posted" with an ETA on fixes.
