Does RDS for PostgreSQL Support Major Version Upgrades?

RDS for PostgreSQL supports major version upgrades.

To upgrade a major version, you can use Data Replication Service (DRS) to migrate on-premises databases to RDS for PostgreSQL running the target major version smoothly. Therefore, you need to prepare a DB instance running the target version before the migration.

On the Instances page, click the target DB instance. On the displayed Basic Information page, click Migrate Database in the upper right corner of the page. If the Migrate Database button is unavailable, contact customer service.

For more information, see Real-Time Synchronization in the Data Replication Service User Guide.
