Hyper-V - Paused-Critical - Out of Disk Space - Can't Merge Snapshots

This is a well documented issue, but I must find a way to fix it in place somehow.  It will take days to move the files off the server to a USB drive and merge separately.  The server only has USB 2.0.

The disk where the VM is stored has no files except the  .vhdx and the .avhdx files, I can't make any more space there.

I do have enough space on the server to move just the .avhdx files, but documents say they must live with the main in the same directory and disk.

There are four (4) .avhdx files, and I assume they must all remain present.

Please help

Thank you very much for the input.

Not that it changes anything, but there is only ONE VM and it's large (1.5TB)  so it's all going to take a lot of time.

Well USB2 can still push 480Mbits/sec. So with a good drive, assuming internal drives are not an option, it is still a few hours. That isn't a terrible maintenance window, all things considered.

I may have created enough room on another disk on the server.

1.  How should I move the VM and it's snapshots to the new location, and start it up?
     a. Can I just copy them to the new disk and do a new server and point to them?
     b. Or will the snapshots not now point to each other and the main?

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
