I currently have a single instance of Exchange Server 2003 Standard installed on a network running a mixture of 2000 Server and 2003 Server. The machine it's running is an older machine with Windows 2003 installed that I'm replacing. My intentions are to load the new server with the operating system and Exchange then migrate the data and users to the new server. I only have 50 users so I could do the migration in an evening assuming all goes well. Considering Exchange 03's integration with Active Directory, I'm apprehensive about installing another server on the same domain. My question is basically can I simply install another occurence of Exchange 03 on the same domain without creating problems? If this isn't a good approach, should I consider creating another domain to migrate the users to? I'm essentially replacing my entire network with new servers with Exchange being a portion of it. I'm planning on migrating the data to the new server using the Exmerge utility and was wondering if this seemed the best approach.
Any help or advice is greatly appreciated! - Dan
