Space needed to hold the mailboxes is only one potential challenge although practically speaking, most folks don¹t get much better than a 1.1 or 1.2 single instance store ratio so the ?more disk space will be used¹ issue is usually overblown. A bigger issue could be repliability your email that you just brought into the new environment might generate NDRs when replied to. A Bad Thing ? as they say. Effectively you are creating a new organization with new address schemes (though of course you want to try and ensure they are identical) and new SIDs for the mailboxes. I always worry about repliability when you're trying to import mail from one organization into another. If you absolutely must maintain the same name, a ?safer¹ option would be a simpler one: upgrade the old server in place. Now a couple of things about this: first off, while it¹s supported by Microsoft, but just I¹m not a big fan of anything that munges around the database format, so personally I don¹t care for in place upgrades. Having said that, they almost always work just fine. If you want to be extra safe, meld the two methods: install another server, move the mailboxes, then upgrade in place with no user mail on the server. When done, move the mailboxes back. I like that better if you absolutely must have the same name. Which brings me to the question others have asked: Why? Servers are injected and removed from enterprise environments all the time, and from a client perspective, the name of the server really doesn¹t matter as long as you give a little time for the directory lookups to correct the profiles for you, so why is this so critical to your goals?
