I am preparing a brand new Exchange 2010 server and planning to migrate the mailboxes from the currently active Exchage 2003 server. Both, old and new servers, are joined to the same domain and are on the same subnet. the new server is currently running MS Server 2008 R2. The migration is going to run for up to 21 days.
1) Should the new Exchage 2010 server be a domain controller?
2) How do i set up a bridgehead for Exchange migration (in the above scenario)?
3) How do i make sure the Autodiscover functionality points all current outlook clients to the new server
any other suggestions?
Thank you in advance,
