I need to split up two companies with two different dns (public) domains on one network at the head office. There are several remote users but I plan to use Outlook anywhere for them.
Original AD domain is all 2003 server and single Exchange 2003 server handling everything.
New forest and domain (all 2008 server and Exchange 2010 sp1) for departing company is already built - I'm looking at migration tools and my head is ready to explode.
I have to wonder, for forty users in-house (approx. 75 email users total, might it be just as fast to just create new users on the new domain, flip the PCs over by copying profiles to a temp local profile, then into the new domain after joining new domain and then just import mailboxes that I've exported from the old Exchange server?
What would be the down side to this approach?
Thanks for your time!
