I've got a single Exchange 2003 server that I'm transferring over to a single Exchange 2010 server, mailboxes and all.
The dns name for my existing exchange 2003 server is mail.mydomain.com and at the end of this I want the new exchange 2010 server to be mail.mydomain.com for consistency sake.
I've hit the part in the Microsoft instructions where I am supposed to get an SSL certificate for the new Exchange 2010 server and I want to get one for the dns name mail.mydomain.com but the old server also has an SSL certificate for that name.
Is this going to be an issue. I assume that as long as our DNS servers point to the old server, it won't matter and when I'm ready to change over to the new mail server as the source for incoming and outgoing mail I just change the DNS pointer.
I just want to be sure I'm not missing something.
