I just used lxd.migrate to migrate from LXD 2.21 (xenial backports) to 3.0 (snap). That failed and now I cannot access my containers anymore. Any idea how to fix that?

The migration process will shut down all your containers then move your data to the destination LXD.
Once the data is moved, the destination LXD will start and apply any needed updates.
And finally your containers will be brought back to their previous state, completing the migration.
Are you ready to proceed (yes/no) [default=no]? yes
