Upgrading from Win2003 DC to Win2008 DC

February 15, 2014 at 09:24:12
Specs: Windows Server 2008, 2 Intel Quad Core 2.8Ghz
We actually have an old Windows Server 2003 Standard machine that acts as a domain controller and we want to replace it with a new machine and install Windows Server 2008 Standard R2 which would be our new domain controller. I suppose that a procedure to achieve my goal can be:

1. Install Windows Server 2008 Standard R2 in the new server.
2. Add the domain controller role.
3. Make it a backup domain controller.
4. Promote it to primary domain controller.
5. Remove the old Windows Server 2003 domain controller.

I am not sure if this process is correct because I do not know if there are incompatible issues between the 2 OS versions. I will very much appreciate your feedback.

There is no such thing as a Backup Domain Controller.
There is no such thing as a Primary Domain Controller.

I think you need to brush up on Active Directory and the roles of Domain Controllers before making a change like this. Ideally, practice on a test setup.

You also forgot the step of running ADPREP on the 2003 DC.

I would suggest you spend a little time over at microsofts TechNet and review the upgrade check lists they provide.

Answers are only as good as the information you provide.
