Exchange 2007 to 2010 then to new domain?
We are in the mists of a domain rebuild to reflect our new combined school (and rid ourself of CC3)
Everything is hunky dory, except for working out the strategy with exchange.. I've read a lot on it and its still not too clear in my head.. The best way it seems is to move our exchange 2007 standard server on another to server upgrading it to 2010 but keeping it on the same domain, then migrating across to a exchange server 2010 in the new domain?
Where I get confused is the way the usernames link, i.e. if i admt the users over to our 2008 r2 domain, will they still link to the same mail boxes as they were linked to a different internal domain name? We are going to give the server we are putting exchange 2010 on the new domain the same IP details as our old one so we do not have to reconfigure MX records?
