I'm curious as to how much time it takes to transition 1K email (~200mb/acct) accounts from a locally hosted groupwise 7 mail server to a 2010 exchange server hosted in the cloud. Can you transfer over all old email and contacts? Is it possible to manage this transition so that users can have continuous access to their email? Our bandwith to the internet is 100mbps.
My organization is making this transition—we're a school. Email must be down for 5-7 days to allow for the transition. I'm told by IT that it has to be this way. It sounds like this isn't true, correct? Email could be kept up continuously, and the transition could be done much faster?
