Can you run TMSXE 3.0 and 2.x at the same time? My thought is to move one mailbox to 3.0 in order to test before moving all accounts. I didnt know if anyone had done this or if you just had to hard cut to TMSXE 3.0.
Moving just one mailbox from TMSXE 2.x to 3 while keeping 2.x around is neither tested nor supported by Cisco. I wouldn't recommend it.
