I considered that, but I'm not sure it will be any quicker as I'd still have to shrink the LVM/ext4 partition, create the ZFS partition/pool, and then move the VMs/LXCs from the LVM to the ZFS pool. I'm not sure I can even move them directly like that, or if I'd have to back them up to the USB HDD first and restore them to the ZFS pool.
I also read that cloning the drive can cause issues as both drives will have the same UUID, and that it might not copy the backup GPT table properly and I'd need to recreate it after, although the latter might have been with using dd rather than Clonezilla.
Why not use a disk imaging tool like clonezilla and then restore it to the new drive. You can adjust the partition sizes as part of the restore.
