Import to Hyper-V?

Has anyone setup their Control using Hyper-V? I’m in the process of condensing all my physical machines to one Windows Server machine. Going to Virtualize with Hyper-V.

I’m trying to figure out how to Import the file system to Hyper V as mentioned at the bottom of the Install Doc. I’ve successfully done it in Proxmox, but haven’t quite figured it out in Hyper-V.

Pardon the relative newbie question… any guidance?
