In preparation for building a new S2012 server to host Ex2013, I replaced both DCs (2008 R2) with S2012 but have not changed the functional level (yet). Should I do that prior installing Ex2013 on the new server? My approach is to install Ex2013, figure out how to transition all the action and the files to the new server (I always get lost here somewhere), and then uninstall Ex2007, take the old box off the domain, pull the plug. Besides the functional level question, anything else I should know? Is there an easy guide that can help me through the dark woods of the server transition? Thanks for the help.
