I have a server running Windows 2008 Std and Exchange 2010. This server it's just sitting there without mailboxes but We have the license to upgrade it to Win2008 R2 (sorry, no Win2012 here...yet) My boss want us to start moving mailboxes from an existing Exchange 2007 server in January, but I wanted to upgrade the server to Win2008 R2 first and also start using DAG (passive mailboxes) on the same server.
I think my only option is to do a clean install since its not being used. but I need to double check with the Spiceworks community. Is it Ok for me to do a direct upgrade or do I need to go ahead and do a full clean install?
Thanks folks!
