Upgrading the RDS for Oracle DB engine
When Amazon RDS supports a new version of Oracle Database, you can upgrade your DB instances to the new version. For information about which Oracle versions are available on Amazon RDS, see Amazon RDS for Oracle Release Notes.
Important
RDS for Oracle Databases 11g, 12c, and 18c are no longer supported. If you maintain Oracle Database 11g, 12c, or 18c snapshots, you can upgrade them to a later release. For more information, see Upgrading an Oracle DB snapshot.
