Except for the DB. The official way to migrate from a Lightsail DB to RDS is to do a logical dump and restore.

For MySQL, or if you have a monotonic column in Postgres, that might be doable if you dumped in parallel, but otherwise it’s an unacceptable amount of downtime when you reach the limits of Lightsail.

It is baffling to me that AWS doesn’t offer a one-click option to B/G from Lightsail —> RDS, as that’s a very reasonable growth pattern for many startups.
