Out of nowhere, I got the approval to move our servers to a collo. I'm scrambling to prepare. I'd like to be able to start re configuring some things now, before I ship hardware off.
I'm keeping all the servers on the same subnet to minimize my reconfig (let's call it 192.168.1.0/24). I'll have to change over the local net, though. I want to do that right now, and try to keep the two networks talking all the while. Let's call the new, local subnet 192.168.2.0/24.
Do I need:
two router interfaces in separate subnets? 192.168.1.1/24 and 192.168.2.1/24
two router interfaces in the same subnet? 192.168.1.1/16 and 192.168.2.1/16
After I build the subnets, I'll build an extra site in AD and move a DC to the new subnet. What else do I need? Any guidance will help.
