"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, HyperV VMs
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
Okay, then I suggest setting up a sandbox with the VMs in their own Private network.

From there run through the domain rename process that TechJourney outlines. That looks to be about the best one of the bunch.

Would we do it? Probably not.

We'd set up the above sandbox then run through setting up a new domain, creating a trust, and migrating everything over. In my mind there's a lot less risk.

Oh, and make sure to have System State and known good backups.
