I'm looking to upgrade a client from E2K to E2K3. They currently have only one server which is W2K DC and E2K. We're looking to install a new server with W2K3 and E2K3 but would like to keep the existing W2K server and it's AD in place. The current server will be used for logon, data and printing and the new server will be just for Exchange. I am familiar with installing a W2K3 server into an existing W2K AD but I am not quite sure how to handle the Exchange side of things. I would ideally like to remove E2K from the current server altogether.
Any help or guidance to relevant documents would be much appreciated.
