Please could you tell me best way to solve this issue ..

1 check all old application, server /like old Linux samba, exch2003/ to support 2012 dc
2 all firewall add same rule as old DC /if have domain trust open firewall./
3 prompt to dc and gc the new server
4 check DNS server /DNS forwarder if have/ and AD  logs
5 run BPA for AD and DNS
6 create gpo or startup script to add/change dns settings on client.
sorry my english
