yes to add new server of new version of OS you need to run following

adprep /forestprep (in 2003 Server)

 adprep /domainprep /gpprep com (in 2003 Server)

adprep /rodcprep  

or you can refer the below youtube video for your reference.

Hi Experts
Can you help to instruct me step by step how to
1, down grade PDC to Secondary and
2upgrade Secondary to Primary DC
Tks alot
There is no downgrade or upgrading like there were in NT days. Now you just move the FSMO roles from one server to another. You can do this through any of the tools.

For example open Active Directory Users and Computers on the new Domain Controller, right click on the name of your domain and from the context menu select "Operations Masters".

Under the tabs for RID, PDC and Infrastructure click the Change button. This will change the role to the new DC.

Also, one other Operations Master exists under Active Directory Domains and Trusts MMC. Right click the top level and select Operations Masters, then click change.

The last one is to move the Schema Master and this is more involved.
