Citus formation upgrade path

I've recently upgraded `pg_auto_failover` to 2.0 for the new Citus support feature. I have existing Citus databases registered as the postgres type nodes in pg_auto_failover. What's the proper thing to do to change them into `coordinator` and `worker` type of nodes known to pg_auto_failover?

Do I simply run `pg_autoctl create coordinator` and `pg_autoctl create worker` over existing Citus formations? Or do I need to drop all exiting registration and start from scratch?
