Retire Active Directory server

I want to retire the server that has my primary DNS and Active Directory Domain Controllers on it.  It is a 2012 R2 and I have 2 others with DNS and are Active directory Domain Controllers.  I ran the command nltest /dclist:domainname.local and it find all3 domain controllers with the one I want to retire listed with PDC.  I can't find a way to promote one of the other domain controllers to the primary.  How do I do that.  I don't want to remove the Primary until I have promoted on of the others.  

Also is there anything I need to do with the DNS servers.  The one I want to retire was created when the Active Directory role was installed.

you need to move PDC role, and any other FSMO role, before you demote it.
How to do it by MS: https://technet.microsoft.com/en-us/library/cc816779(v=ws.10).aspx
or little more with pictures :)

As for DNS, check if other servers have forwarders, and how is that configured, so you don't end up with no internet access.

did you verify all the FSMO roles?

Run this command:
netDOM /query FSMO

this guide should help you in the right direction

Ivan--got the PDC role moved to the new server.  The DNS has all the forward lookup Zones that the old server does except the old server lists <servername> and also <servername.domainname.local>  How do I get the servername.local in the new server or do I need to?
