We are splitting up offices and relocating 8 staff to another location. This will become a separate entity, so it will be a different domain name at the new location.
Both offices are currently on a fractional T1 and are about 3.5 hours away from each other. A couple of the users are hitting the 25 GB limit on their mailboxes, so it will be 100-200GB for all 8 users. Should I make the drive and backup to external drive or let it rip all night over the T1's?
Should I use the Exchange Migration, exmerge or is their a better method?
Notes: Old server is SBS 2003 and new server is SBS 2008.
