Upgrade Windows Server 2008 Standard to Enterprise with Exchange 2010 installed
I have a Windows Server 2008 Standard Server which currently runs my production Exchange 2010 System. I would like to implement DAG and this requires the Enterprise version of Windows 2008 Server.
There is an upgrade tool available. Can anyone tell me if they have successfully done this upgrade without breaking Exchange? Or if Exchange does break what steps I need to follow to then fix it?
Other considerations are that we do have a BES server.
