We currently have an Exchange Server 2003 on our network. We are building a new virtual network that will be new from the start....new Domain Controllers, Active Directory.....we are even changing our username conventions.
Migration doesn't seem to be the answer because everything is different including SIDs.
I don't need the mailboxes and permissions and all that baggage, I just need the mail and calendar and contacts.
How can I get this data moved to where I can get it into the new Exchange 2013 server?
Exmerge to PST I have thought about, but it is very, very slow.
