Migrating from Exchange 2003 to 2010. I see the directions call for three domain names:
mail.domain.com (new Ex2010 server)
legacy.domain.com (new DNS record to be pointed at soon-to-be old Ex2003 server)
Currently, I have the old Ex2003 server as mserver.domain.com. The new Ex2010 I want to call mail.domain.com and NOT mserver.domain.com. From what I can tell, I think I'm going to have to visit each client personally (or remotely) and change the principal (MSSTD:mserver.domain.com)
name to be the new principal (MSSTD:mail.domain.com). Anyone know a way around this? In the long term, I want mserver.domain.com to go completely away.
The cert I'm using has mserver.domain.com as the primary name, and mail.domain.com as a SAN. Therefore authentication fails using www.testexchangeconnectivity.com
and the test for RPC/HTTP. The failure reads, "The certificate common name mserver.domain.com, doesn't validate against Mutual Authentication string provided msstd:mail.domain.com". I know I can change the mutual authentication string in Exchange Mgmt Shell, but this doesn't help me when I want to retire the DNS name mserver.domain.com.
