I've been looking all over for the easiest way to move our install of Exchange 2007 SP3 on old hardware running Server 2003 R2 to new hardware running Server 2008 R2 or Server 2012 R2. I have two questions. Should I go to Server 2008 R2 or should I take it to Server 2012 R2? Can anyone recommend some HOWTO or documentation that will outline what I need to do?
Our present exchange server is accessed by Outlook 2010, OWA and various smartphone. It is not a deal breaker but I would prefer a method that would not require any client reconfiguration. Taking the server offline over a weekend can be done.
I appreciate any suggestions
