i have all my servers running Server 2012 standard including my DC .... im going to install another DC which will then be my primary DC and the old one will be for redundancy..
Question is can i install Server 2012 r2 for the new DC? or does it have to be Server 2012 standard also..
Also im going to move fsmo roles to the new DC so this will be primary - do i have to or can i raise the forest functional level within AD?? will i have to do this on the old server 2012 DC?
