Morning, I am in the process of planning for a domain migration. I currently have 2 Exchange 2010 servers with mailboxes databases residing on both. The connection between the 2 servers is extremely slow so migrating the mailboxes takes an extremely long time. I am wondering if I can leave simply migrate the entire exchange server over to the new domain WITHOUT having to migrate the mailbox database? Say I setup a new site with a different subnet, then associate an exchange server with that site. I then would setup a new 'Accepted Domain' as a internal relay so both servers can receive email from '@domain.com'. MX records would point to 1 server only. Is this a feasible solution or am I just stupid. Noncentznoncentz

Hiya, You've asked this in the Exchange 2013 forum rather than the Exchange 2010 forum, but as a quick answer - If you're doing an Active Directory domain migration - No, you'll need to move the mailboxes over. It sounds like you are, as if the Exchange servers were part of the same AD domain, then the Accepted Domains (as in domains you use for SMTP, irrespective of AD domain name) would already be available to both servers.

Oh Geez, sorry about that! You are correct that the Exchange servers would be the in the same AD domain so Accepted Domains would not work... well I guess I already kinda know my own answer! Cheers, Noncentznoncentz

Sorry, are they in the same AD domain or not? If they are in the same AD domain (or even AD forest) they are part of the same Exchange organization and share accepted domains. SteveSteve Goodman Check out my Blog for more Exchange info or find me on Twitter
