This page exists to detail the process of moving the server roles of AMADEUS to DVORAK.It will detail what has to be moved, how to do it, and any other steps that need to be taken to move all operations from a Windows Server 2008 machine to a different machine running Windows Server 2008 R2. However, the steps should be that same for moving between any 2 NT6 based systems.

This was done not with a straight migration, but by adding the new machine as an additional controller in the existing windows ADDC forest.

Step 1: Preparing the existing forest for an additional controller

You will need to run adprep.exe or adprep32.exe, for x86 systems, on the original server. Aprep can be found in \sources\adprep in the Windows Server 2008 install disk. Run an instance of the command line as admin and navigate to the folder containing adprep.exe, then in the command line run:

adprep.exe /forestprep
adprep.exe /domainprep

The current forest should now be prepared for an additional controller
