change IP Address of domain controllers to match old IPs

-

dears,

i have 80 ad sites, in ho have 2 dcs 2003 sp2  "dc01 , dc02", , 1 dc in each branch site,  introduced 2 new domain controllers 2008 r2 (dc03, dc04) in ho , want swap ips new dcs match ip address of old dcs 2003  in ho...will break replication between branches & ho ? since branches dcs have dc01 or dc02 replication partners , i'm afraid once change ip address  branches dcs can't communicate replication partners  dns name resolved wrong ip

your appreciated...

thanks,

branch dcs accept incoming dns replication fbecause it's authenticated.

you can use scenario minimize replication risks

1. set dc02 bridgehead server

2. swap ip-addresses between dc01 , dc03, run ipconfig /registerdns , dcdiag /fix

3. check replication status

4. set dc03 bridgehead server

5. swap ip-addresses between dc02 , dc04, run ipconfig /registerdns , dcdiag /fix

6. check replication status

you should check firewall settings before operations.

after change ip address of domain controller, should run ipconfig /registerdns command register host record , dcdiag /fix command ensure service records appropriately registered dns.
