We're introducing a new exchange server for several reasons. After the introduction of the new server, and synchronizing it with the old one (mailboxes, contacts, rules, the whole shebang) we're going to be formatting the old machine, install XenServer 5.5 on it, and create a slices, one of which will have Exchange server, which again will need to be synchronized. Then, we'll have 2 different routes to the mail servers (mx1, mx2) so that if there is an outage on one, the other should be available.

So now, I'm wondering how to synch? I can move a mailbox from one server to the other, and I'm sure that can be done in bulk, but that's not what I'm looking for. I'm looking to make both Servers equal, the first time so I can make a backup of the original, and the second time so that they can be made into peers.

This is with Exchange 2007 on Windows 2008 R2 (x64)

Suggestions?

TIA
