How can I move a container to a different project on the same server without incus re-copying the container data?

Using Incus 6.20 on Ubuntu 22.04 & ZFS

I’ve tried a few different ways but cannot seem to figure out how to move a container between projects on the same server and using the same storage pool without those containers being re-copied.

I would think that the container meta data would be updated, but not re-copied if doing so was not necessary.

The commands I’ve tried:

incus move c1 --project old-project --target-project new-project
incus move c1 --project=old-project --target-project=new-project
incus move c1 --project=old-project --target-project=new-project --storage=default
incus move c1 c1 --target-project new-project

I may have also tried a few other combinations.

Each time, though, the full container is copied

In case this makes any difference, the server is the migration server I used when migrating from LXD to Incus. So these containers started out on LXD, but were migrated to Incus using the migration tool.
