root@lantea:~# snap install lxd --edge && lxd.migrate -yes
2019-11-19T20:35:09Z INFO Waiting for restart...
lxd (edge) git-2b837b6 from Canonical✓ installed
=> Connecting to source server
=> Connecting to destination server
=> Running sanity checks
The source server is empty, no migration needed.

The migration is now complete and your containers should be back online.

All done. You may need to close your current shell and open a new one to have the "lxc" command work.
To migrate your existing client configuration, move ~/.config/lxc to ~/snap/lxd/current/.config/lxc
