Changed domain controller IP and gateway.. having DNS issues now

Changed domain controller IP and gateway.. having DNS issues now

Changed domain controller IP and gateway.. having DNS issues now

(OP)
Hello. We had two offices VPN'd together with the same domain name.

Office A-
Domain Controller 1: 10.29.2.215
gateway: 10.29.2.4
Handled all 10.29.2.x addresses

Office B-
Domain Controller 2: 10.29.3.15
gateway: 10.29.3.4
Handled all 10.29.3.x addresses

We finally merged everyone into a single office and I'm trying to merge our networks together. For various reasons I need to keep the 10.29.3 IP scheme. I changed the DC1 ip from 10.29.2.215 to 10.29.3.215. Changed the gateway from 10.29.2.4 to 10.29.3.4.

I think I'm still having DNS issues. Do I need to go through some 'start over' steps on my DNS? I still see my 10.29.2 zone out there. I still have the 10.29.2 in reverse look up.

I'm sorry, I'm aweful with DNS. Are there some steps I should go through when making a change like this?

Thanks!

Brian
