Apologies for the very long hiatus on this topic.

I finally got back into trying to troubleshoot this problem, and while I don't fully understand why or how, I believe that replacing the key on the new flash drive, then installing the license correctly on the server fixed all of these issues.

Up until that point, nothing I did worked.  I tried copying files one at a time from the old backup, but copying basically any functional part of my old config to the new drive would result in the same problem, GUI being unavailable, and several other things not working either (no Docker containers visible, no VM's, no shares...)

All fixed as soon as I went through the key replacement process for the new drive and blacklisted the old.  After restarting the server, I'm golden - GUI available at the old URL, domain address is working, and VM's, Docker containers and shares are visible and configurable again.

I really appreciate everyone's help trying to sort this out.  No idea how to best note this for folks that come to this thread with similar problems, but replacing the key on the new drive to register it to my account is what did the trick. 

This also means that the USB tool probably did work, and I just needed to go through replacing the key before troubleshooting the issues I ran into.  Would have saved me months of pain.
