Active Directory Migration

Posted on 2004-11-04
Last Modified: 2010-04-19

At present I have 3 DC running in a Windows 2000 environment.  The PDC,ABC, is running Windows 2000 Server, another DC, ABC1, is also running Windows 2000 Server and the Exchange 2003 server, ABC2, is running Windows 2003 Server.

I would like to create a new domain.


Take the machine that is called ABC1, and scrub it and install Win2k3.  It
would therefore act as the PDC in the new domain, TESTING.COM

Install an Active Directory Integrated zone

Create a trust relationship between old domain,TEST.COM and new domain, TESTING.COM

Install Active Directory Migration tool in the new domain created.

Move the user account and groups to the new domain

Install the Exchange Migration tool in target domain

Move mailboxes to new domain

Uninstall Exchange 2003 from the server called ABC2


Add it to new domain

Reinstall Exchange

Remove the server called ABC, install WIN2K3 on the server and add to the new domain

Transfer role of PDC emulator back to this system

Is this plan doable to create the new domain.
Is the process correct for adding the server which presently has Exchange on it to the new domain
I would like when the server running exchange is added to the new domain it is a Member server, how do I achieve this.

Are they any steps I am missing to accomplish the goal.  Any advice would be greatly appreciated.

    There could be an easier way, why are you creating a new domain?  I want to make sure I know if I can help before I go into a big explanation.

    Presently all servers in the environment are running as DC's and they are a combination of Windows 2000 and  Windows 2003 Server.  We were initally thinking of using the domain rename tool, but that requires that Exchange not be running on a DC.

    That is why is was moving towards using migration.  Also management wants to have the new name for the domain so it reflects more of the company image.
