Moving all of my Windows 10 VMs from a 2TB hybrid drive (sda) to a 512GB NVME (nvme1n1). This only worked so easily because the Windows system partition was only 160GB to begin with, so it was going to grow instead of shrink.
The original partition map on sda was as follows:
label: gpt
label-id: DF9036C3-BB74-4013-B1DE-B4E3B60B9BC3
