I would like to make a duplicate of our current exchange server that I can take offline from the network and do testing with. Currently I have the main server replicating to another server that is the test server. I’ve looked at the technet article on forklifting users to a new server. However I’m concerned about downtime. Can anyone recommend a method to do this? I don’t have to have all the public folders or mailboxes, but I’d like some of them to be identical. Thanks!
