We are about to migrate away from a class C ip structure (192.168.100.x) to
class B (http://www.subnet-calculator.com/subnet.php?net_class=B
I was basically planning on coming in on a weekend and going around and
changing all static ips to their new class B version..
Our domain is 2008 R2, with two DC's, two DNS and one DHCP.. I was going to
create a new scope reflecting this new class.. then deactivate the old dhcp
and activate the new one.. having everyone power down friday before leaving,
so monday they will get the new class B address..
In changing the ip's on the DC's (with dns/dhcp services).. are there any
things i havent thought of, that i should be doing as i make these changes..
I'm thinking i may have to change some dns records related to the domain/AD
and these DC's manually..
Everything we do is ran off of two Hyper-V virtual server hosts as well.
(with virtual nics).
Any thoughts.. has anyone gone through this changeover.
