change RODC to full AD

Hi Experts,

I just want to verify my next project with you.
We have a RODC WIN2008 in one site.
Now we upgraded the WAN Spped to fibre.

When I want to change the RODC to a full AD, what kind of steps I have to think about ?
And in which oder ?

I know I can demote the RODC and install a new AD with dcpromo.
Is this all or do I have to some pre steps and post steps ?

You can't just convert from one to the other. You'll have to demote the RODC (completely remove all DC properties from the server) and then promote it to a regular domain controller.

So long as your normal domain controller is running, there shouldn't be any special steps you need to take.

ok, the normal one is running.
But what about the user logins ?
The users in this site are pointed to this RODC.

If this is an active directory site then they will use the local DCs in that site so if there is a full DC there they will use that.


Thanks

This would be something that you'd want to do after-hours (or during a scheduled time, if there are users 24/7), assuming you can't temporarily point them to another DC. Unfortunately, there's not much that you can do about that.

yes it is.

So it is enough to uninstall all DC related stuff and install a new DC in this existing site ?
All with dcpromo of course :-)

Then Right you will dcpromo to make it a member server again/remove RODC.  Then promote it again to a full RWDC.

When you dcpromo down just spot check DNS to make sure the old RODC records/references are gone

Thanks

Agreed, this should not be a problem for you, (especially since you're keeping the same IP address) so long as you can do it when the users aren't going to be using the server.
