I need some clarification on the names needed for the UCC/SAN certificate for an Exchange 2010 transition. I have the following: 1 front end Ex2003, 1 back end Ex2003, 2 new Ex 2010 with CAS, HT and Mailbox on both boxes. These boxes will have a CAS array w/ no load balancing and they will have DAG.
What names will the new cert need? if it needs the legacy.domain.com name, do i physically need to change the 2003 server names to legacy? if so, which one front end or back end? when i create the cert request, which new Ex2010 box do i do it from? does this cert need fqdn's of both new servers? do i need to create a new certificate for the legacy box that changes its name to legacy? I need a lot of clarification on all of this naming convention changes and the naming needed for the certificate(s). thanks in advance
