I have 5.5 installed on 2 machines; same site; same DNS. A third machine is the DNS controller and PDC. I want to get rid of machine #1, which hosts 5.5 and is the primary exchange server; replace it with a new box. Since machine #2 is also running, can I just get rid of machine #1; build new machine - bring it back up with same I/P and same exchange server name- and be back in business with exchange? I really want to get rid of the exchange server from box#1; and replace it with a new box (computer)- is the above the easiest way to do it = as far as exchange is concerned?
