I have a small network with one 2008 DC and 2 2003 DCs. I have existing Exchange 2013 SP1 on a 2012 R2 member server. I want to install a new 2012 R2 DC and demote/decommission the old 2003 DCs. This is a single site.
Everything I have read says that the Exchange 2013 SP server and 2012 R2 DC should be compatible together. Are there any gotcha's i should be concerned with when i promote the 2012 R2 server to a DC?
