3.1.2.2 Server Upgrades

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

• Patch versions, such as 9.x.N: Upgrades to them must be performed manually (except when there is an automatic upgrade due to version removal). See Upgrade MySQL Version for information.

• HeatWave-specific versions, such as 9.x.y-uN: Upgrades to them are performed automatically and according to the maintenance window defined on the DB System.

For more information about MySQL Server versioning, see Server Versioning.

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