I am migrating from an existing Exchange 2000 server (lets call it Server1) running on W2K to a new Exchange 2003 Server on W2K3 (Server2). Native AD domain. Mix of 2K and 2K3 servers, though the master AD Controller is a 2K server. The existing Exchange server, Server1, is also an AD Controller. The new Exchg2003 server will not be an AD Controller.
I have completed all of the steps in the Exchange Server 2003 Deployment Tools, including all necessary domainprep and forestprep actions. All passed.
When I actually begin the Exchange 2003 install on the new server, it returns the following message:
'The component "Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action "install" because:
- All Active Directory Connectors in the Windows forest must be upgraded to the most current version before you can upgrade Microsoft Exchange. The following ADC servers have not been upgraded:
I believe the solution was provided in this post:
However, given that the old email server (server1) is an AD Controller, and will continue to remain active in that role, should I really remove the AD Connector from that server?
Also, as a side question, I've read somewhere that it's preferable for Exchange 2003 is NOT installed onto a machine which is an AD Controller. Is this correct?
Any input will be greatly appreciated!
