I would like to know in a few simple steps what I am supposed to do about certificates when migrating to Exchange 2010. This is the setup:
1. We have 1 Exchange 2003 server
2. We are implementing 2 Exchange 2010 servers in a CAS array with DAGs
3. We will then be moving mailboxes across to the Exchange 2010 servers in our own time.
Now I know I need one of the new SAN certificates with the domain multiple names but then what? I have 2 CAS servers so can I import this same certificate to both servers if so how?
What do I do about the Exchange 2003 server do I need to import this new certificate here? if so how? Will users get prompts to accept new certificates in Outllok and over activesync?
I can't find good documentation for this anywhere, please help!
