I am about to help a client migrate their Exchange Server to newer hardware on the same box - new SATA Raid replacing IDE-ATA drives. I will do this by loaning them a server to hold email while I rebuild & reload their old server with the new drives. I have Server 2003 on the loaner server, and after I made it a member server to their AD domain, I loaded Exchange 2003 + SP2 on it.
When I've finished this migration, I want to use this same loaner pc for another client. Apart from removing the box from their domain, and attaching to the new domain, what do I need to do in order to "re-use" Exchange? Are there steps that remove the data (all mailboxes & configuration)so I can put it in another AD domain, or do I do a complete uninstall/reinstall of Exchange and add the service pack again? Or is it even worse, and I must totally reload Server 2K3 as well as Exchange?
