You want to do a swing migration. With careful planning it can be done with zero downtime to the users. A real rough outline of the process: Install Windows 2000 in the usual way with a unique name and add it to your existing domain. Install Exchange 2000 from the CD. It will join the existing Exchange organisation. Setup replication of public and system folders. For system folders, basically follow the steps in this article up to but excluding removing the existing Exchange server. http://support.microsoft.com/default.aspx?kbid=307917 Then use the "Move Mailbox" wizard to move the mailboxes across. As long as both servers are available when the clients connect for the first time, they will be automatically redirected. Once everyone has redirected, remove the replicas of the public and system folders - basically follow the article above to remove Exchange correctly. If you know your way around Exchange then I have an article on my web site at http://www.amset.info/exchange/migration.asp which goes in to it in more depth. However it does not tell you how to do each stage in baby steps, it presumes that you know how to configure replicas and other tasks within Exchange.

We currently have Exchange 2000 running on our root domain controller. There is a request to install Exchange on a new server. Here is our setup: CURRENT SETUP: - Exchange 2000 (SP2) running on root domain controller which has DNS, DHCP installed - GFI Mail Essentials installed - NAV for exchange installed - Exchange server behind ISA 2000 which publishes OWA WHAT WE WANT TO DO: - Move Exchange 2000 to new server + GFI + NAV with the least amount of impact to Active Directory and Outlook client. What is the best approach? I am trying to do the planning for this and want to have all possibilities and eliminate as many head aches as possible.
