Im looking to redesign my ip address scheme across 9 sites, with 1 main site called a
current dns setup, is all sites point to site a for dns forwarding and site A forward requests for extneral dns to the isp
dns is fine across the whole network.
site A hosts all the fsmo role across 2 domain controllers.
the remaining sites 6 have single dc setups, and 2 have 2 dcs at each site. all in standard configuration.
every site is in a different subnet, 172.21 / 172.22, etc
i need to do 1 site at a time starting with site A,
is it as simple as, add routing to route everything to site A's new range,
change master DC ip address, and run dcdiag /fix to update all the dns service records.(repeat on second dc in same site)
clients on site a would have a new range pushed via a dhcp scope
