I currently have exchange 2003 running on an older server. I purchased a new server and I am going to install exchange 2007 on it. I would like the same server name on the new server as the old server if possible. Granted I can't have both on the network at the same time if they have the same name. Should I name the new server something like exchange1, join it to active directory, install exchange 2007, move mailboxes, kill the old exchange server, rename the new server and switch the ip address to the old name and ip or would that cause too many problems? If that might cause problems would you just leave the name as exchange1 and just switch the ip address? How would you go about the installation/configuration. Any recommendations would be helpful. I also wouldn't have to move the mailboxes as they are pretty much test mailboxes but would like the practice.
