Seems that section is expanded since I last checked it. We may be able to work out something so that PVE nodes export a NFS share to ESXi nodes, so that big disks can be migrated there and then converted in the background. We'll check first with a smaller VM. I will report back if we finally start this project, thank you!

Some of the issues we could fix removing VM snapshots from VMWare, but others (with the biggest disks, about 3,5T) prevailed, even after checking for snapshots (no snapshots present) and trying to flatten the disk image. Those were file servers and we had to fail back to copying disk contents with robocopy, and fippling VMs to minimize downtime; a procedure that has its issues.... > > In the new migration, we have a pair of VMs with 12TB disks, and one with 35TB.
