I have spent the last couple of weeks getting my small used PC into my Proxmox server and it’s going great! …Until I quickly ran into the 256GB SSD size limit of the included drive. So I have ordered a much larger (2tb) one so I can expand much more.

Ideally, I would like to make an exact clone of what I have now just on my bigger SSD to avoid having to rebuild my VMs

One issue is that the computer has room for one drive only. I was hoping to get an exact clone to a USB drive then clone to the new drive once replaced with the new one.

Any suggestions or tips would be appreciated, thank you.
