Best method to restore backup VM on new pool/hardware?

[NadoNate]

Hello,
I've run out of room on a single SSD / ZVOL i use for a VM. I've orderd a second SSD in an attempt to expand my available space.

What is the best way to backup and restore my ZVOL?

I've created a snapshot and sent it to a different local pool following the suggestion here: how-to-backup-and-restore-a-vm.109523/

At this point I want to delete the existing VM-ZVOL, add the new hardware, create a new pool/ZVOL using both SSD's.

How would I than restore my backup using my snapshot clone? Am I misunderstanding that clones are deleted after the origional dataset is destroyed?

For anyone curious, I was able to accomplish this by:

1. Create snapshot of the zvol with the VM - zfs snapshot pool#1/zvolname@snapshot-name
2. Clone the snapshot to a seperate pool - zfs send pool#1/zvolname@snapshot-name | pv | zfs recv pool#2/dataset/zvolname
3. Destroy the (original) snapshot - zfs destroy pool#1/zvolname@snapshot-name
4. Export/Disconnect pool#1 and disk through the UI
5. Add new hardware and create new pool#3 with expanded storage through the UI
6. Push the cloned zvol/snapshot to the new pool - zfs send pool#2/dataset/zvolname@snapshot-name | pv | zfs recv pool#3/newzvolname
7. Recreate the VM (add) selecting the new zvol as an existing disk:

At this point the VM boots. I had to create a partition with the new space, add the partion to the LVM group (i'm using Ubuntu 22) and use resize2fs to make the OS recognize the new available space.
