I am installing Exchange 2007 for the first time and following a set of instructions that have been very helpful. I am at the point to where I am beginning to move mailboxes over from my legacy system to Exchange 2007. My question is after the mailboxes are moved and I have finished decommisioning the old exchange server--can I rename the Exchange 2007 and call it the Computer Name of the old exchange server without any problems? For example, the present old exchange server is called Server1 and the New Echange 2007 server is called Server2. I would like to rename the Server2 and call it Server1.
