Windows Server 2008 Release 2 (R2)
UMove is fully compatible with Windows Server 2008 Release 2 (R2).
Upgrading from Server 2008 non-R2 to Server 2008 R2
If you want to replace your old computer running Windows Server 2008 (non-R2) with a new computer running Windows Server 2008 R2 (W2K8R2), you can use UMove to to move Active Directory from the non-R2 server to the R2 server. The old computer can run either the 32-bit (x86) edition or the 64-bit (x64) edition of Windows Server 2008.
Before you can run UMove to move AD to W2K8R2, you first must prepare the Active Directory schema by running adprep. This is explained in Microsoft's instructions for installing W2K8R2.
You must run adprep on the non-R2 server before you capture the snapshot of AD from it. This is because the snapshot of AD must contain a copy of the R2 database schema in order to be loaded successfully into the R2 server. (UMove will warn you if the snapshot does not contain the R2 schema.)
The instructions for running adprep are given below.
If you already ran adprep on the source (non-R2) computer you can skip the procedure.
Prepare the AD Forest and Domain
Prepare Active Directory to run on Windows Server 2008 R2 (W2K8R2) for the first time.
- Apply the R2 schema update to the existing Active Directory. On
the old Windows Server (non-R2)
domain controller (DC) that owns the
Schema Master FSMO role, insert the W2K8R2 DVD disc and type the following:
- cd /d D:\support\adprep
- adprep /forestprep
netdom query fsmo .
This will apply the R2 schema update to the AD forest.
- Apply the R2 domain update. On the Windows Server (non-R2) DC
that owns the Infrastructure Master
FSMO role, insert the W2K8R2 DVD disc and type the following:
- cd /d D:\support\adprep
- adprep /domainprep /gpprep
This will apply the R2 security and group-policy updates to the domain.
The above procedure is the same one that Microsoft instructs you to follow when upgrading to W2K8R2.
More Information
For detailed information on using adprep see the command reference.
If you previously installed Windows Server 2008 R2 on another DC in the domain
you do not need to run
You only need to run adprep once. It is not harmful if you run adprep multiple times or run it on the wrong DC. It will display an error message and quit without changing anything.
If you forget to run adprep, UMove will display a warning message to remind you.
