DC Demotion

I promoted a 2008 DC at a site about 2 weeks ago.  I'm preparing to demote the 2003 DC at that site.

Here's what I've done so far:
Verified it is not holding any FSMO roles
Made the new DC a GC
In the process of transferring DHCP
Installed DNS on the new DC
Verified replication with repadmin /showrepl, always successful
No errors on new DC

Anything else anyone can think of checking before doing the dcpromo on the old DC later this week?

You'll need to point all of the clients DNS to the new DC that were pointing to the old but other than that - looks good to me.

Would recommend you run a dcdiag on the new server and assuming all is well, turn of the old DC for a couple of days BEFORE demoting it. This will prove that all is well. If still no errors then power it up again then demote.

Thanks for pointing out the DNS settings, I do have that configured already on the new DHCP server that I'm transferring to.  But a reminder never hurts.

Could you help me with the dcdiag commands?  I use it so infrequently that I forget.

don't forget any devices that have statically assigned addresses.

As for DCDiag, log into your new dc, fire up a command prompt and type...

DCDIAG

Everything should say "passed"

Yeah, DcDiag looks clean, except for this:

But since I'm still running a 2003 functional level domain, cannot add a RODC, and have not run adprep for 2008, I guess I would expect this error.

All appears well!

I would now recommend switching off your old DC and making sure everything still works (which it should) and if so, leave for a few days the run the demotion.
