We have upgraded to Windows 2003 AD from NT 4.0 and still have an old BDC that used to be a PDC prior to the upgrade. I want to use the BDC as a member server but need to make sure that it doesn't receive any directory updates. I realize that I can demote it using a tool called UPromote, but don't want to go that route.
I can get to the dialog box where I can change the functional level and can see the warning after I click "Raise". The question is: is it safe to simply raise the Domain Functional Level to 2003 Native, or are there any additional steps involved?
