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:                   192.168.1.5
SM:                 255.255.255.0
GW:                192.168.1.1

PRi DNS:        192.168.1.5
ALT DNS:        192.168.1.6

DC02
IP:                   192.168.1.6
SM:                 255.255.255.0
GW:                192.168.1.1

PRi DNS:        192.168.1.5
ALT DNS:        192.168.1.6
