I will be doing a migration in about two weeks time for about 45 users. Most are in house but some are remote workers. Biggest problem I'm going to face is that their only pipe is a single T1. I also found a user with over 11GB of email.
I was thinking of setting up enabled accounts just to get all new mail to come over, but currently their MX records are pointed at their old POP3 service. I won't be changing those until the day of migration. Since it is POP3 I know it won't pull over their current folder hiearchy for their Inbox (or will it?). Also, will this also take the email off the existing POP3 server so they wont' see it on their old account?
At least this could give me a head start.
Any ideas?
