R2: Windows Server 2003 Release 2

UMove is fully compatible with Windows Server 2003 Release 2 (R2) and with Small Business Server 2003 R2.

Upgrading from non-R2 to R2

You may need to replace your server with a newer computer on which you plan to run Windows Server 2003 Release 2 (R2). You can use UMove to to move Active Directory from an old computer running Windows Server 2003 (non-R2) to a new computer running R2. The procedure is shown below.

If R2 was already installed on the source computer, you can skip this procedure.

1. Prepare the destination computer: Install Windows Server 2003 Release 2 (R2).
2. Install UMove on the computer and load Active Directory.
3. Add the new R2 object schema to Active Directory:
   • Insert the Windows Server 2003 R2 disc.
   • Run D:\CMPNENTS\R2\ADPREP\ADPREP.EXE /forestprep
     (The exact path will vary.)

This will apply the R2 object schema to Active Directory.

You only need to run ADPREP on the DC that owns the Schema Master FSMO role. This is usually the first domain controller installed in the AD forest.

If you previously installed Windows Server 2003 R2 on another DC that has the Schema Master FSMO file, you do not need to run ADPREP. This is because the other DC has already run ADPREP and installed the R2 object schema into AD.

You only need to run ADPREP once. (It is not harmful if you run it multiple times.)

To determine if ADPREP was already run see KB917385.
