MySQL HeatWave on AWS supports the most recent release version of MySQL.

  • Minor versions, such as 8.0.nn, must be applied manually. See Section 3.3.4, “Upgrade MySQL Version” for information.

  • Upgrade versions, such as 8.0.nn-un, are applied automatically and according to the maintenance window defined on the DB System.

It is not possible to roll back (downgrade) an upgrade. It is recommended to perform a full backup before upgrading your DB System.
