Moving snapshots between lvm-thin pools

[Agent92]

Is it possible to move snapshots between lvm-thin pools?

I recently moved the disk for one of my vm:s to a new storage pool but I would also like to move over the snapshots. I know moving snapshots between different storage systems is a problem but this is between two lvm-thin pools.

As of the Red Hat Enterprise Linux 6.5 release, you can create a thinly-provisioned snapshot of a non-thinly-provisioned logical volume. Since the non-thinly-provisioned logical volume is not contained within a thinpool, it is referred to as an external origin. External origin volumes can be used and shared by many thinly-provisioned snapshot volumes, even from different thin pools. The external origin must be inactive and read-only at the time the thinly-provisioned snapshot is created.
