Issue description

How to migrate containers on the old version of lxd? My containers are all in the lxd-zfs storage pool, but I have added a new storage pool my-zfs. How do I copy a container from lxd-zfs into my-zfs?

Because my lxd version is older, 3.0.3, there is no -s option in lxc copy or lxc move

Because it is a production environment, I can't upgrade my lxd version. Is there any other way to achieve it?

Steps to reproduce

1. Step one
2. Step two
3. Step three

Information to attach

• [ ] Any relevant kernel output (dmesg)
• [ ] Container log (lxc info NAME --show-log)
• [ ] Container configuration (lxc config show NAME --expanded)
• [ ] Main daemon log (at /var/log/lxd/lxd.log or /var/snap/lxd/common/lxd/logs/lxd.log)
• [ ] Output of the client with --debug
• [ ] Output of the daemon with --debug (alternatively output of lxc monitor while reproducing the issue)

Support requests should go to https://discuss.linuxcontainers.org

In this case, the server-side support for cross-pool migration came with LXD 4.x, so that's missing in your 3.0.3 installation. You may still be able to do it through lxc copy by making use of a profile defining the root device to be in a different storage pool,.
