Hi 
we are planning to do domain controller migration from 2008 R2 to 2016 
my question is before promoting the server to domain controller 
what should be the primary DNS on NIC (DC02)? 
point to itself? point to old DC? or 127.0.0.1? 
 
after the migration we are planing decommission the old server (DC01) 
 
DC01 
IP: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 192.168.1.5 
SM: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 255.255.255.0 
GW: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;192.168.1.1 
 
PRi DNS: &nbsp; &nbsp; &nbsp; &nbsp;192.168.1.5 
ALT DNS: &nbsp; &nbsp; &nbsp; &nbsp;192.168.1.6 
 
DC02 
IP: &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 192.168.1.6

additional domain controller NIC DNS

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
