Rebuilding Hyper-V

I'm running Hyper-V on a 2012 R2 server.

I need to rebuild this 2012 R2 server fresh and join to a new AD domain but the host name and IP will remain the same.

What would be the best way to restore the Hyper-V configurations and the VMs?

Do I just backup and restore the Virtual_Hard_Disks (has all the VMs) and the Configuration_Files\Virtual Machines folders then in Hyper-V settings, re-point the Virtual Hard Disks and Virtual Machines to the restored location?

And is there a way to backup and restore any other settings hyper-v related settings such as the Virtual Switch settings?

Thanks
