Installing Hyper V on a DC to migrate DC roles to VMs

[CaptainSpooderman]

Hi all,

I have taken on a small side project to get more experience in sysadmin. I had configured a server with Server 2022 installed and configured Active Directory before moving the server to where it needs to be.

I also started preparing for my AZ800 exam alongside it and just discovered its best practice to have 2 DCs, and to use Hyper V to host them. I want to be able to do that, but, as I said, I have already configured AD for it, with the GPs as well. 

What I want to know is, if I installed Hyper V Manager on that server, can I create a VM for another DC and have it replicate AD data to it, transfer FSMO roles to the VM, and the demote that server so it only acts as a host for Hyper V VMs and then create another DC VM.

Is that possible, or would it be better to just reinstall Windows and try it again? 

Thanks again, and sorry if I sound like I dont know what I am talking about.

Is that just a playpen area?
I hope you do not use it in production?!!!
Normally you have at least 2 DCs in any network, on SEPARATE hosts (ideally one physical & one as VM on whatever hypervisor you use)

If you are jus playing, then you can do what you stated
