For end-to-end instructions on how to perform each type of database migration, see:
AWS RDS PostgreSQL or AWS RDS Aurora (PostgreSQL compatible) database to an HM-managed database
Self-managed Postgres database to a different self-managed Postgres database
Other Postgres sources, such as EDB Postgres AI Cloud Service (formerly BigAnimal), are also supported and follow the same self-managed Postgres migration path. In general, any self-managed Postgres database is a valid migration source, regardless of where or how it's hosted. For the full list of supported sources and destinations, see Supported databases and operating systems.
