hi, performing cross-forest migration from exchange 2003 to exchange 2010, where exchange 2010 already exists in the target forest, what is the best way to migrate calendar and schedule/free+busy?
On the subject of MRSProxy above you mention; "This works even if the source mailboxes are on 2003 or 2007 MBX servers as long as an Exchange 2010 CAS server exists in both organizations", just to confirm i need to deploy a 2010 CAS into my source org, to perform mailbox moves?
Also, is there an accurate way of calculating the time it will take the move request to complete; obviously depends on mailbox size, but a 2gb mailbox over a 4MB WAN link, lets say.
your help is greatly appriciated.
Thanks.
