3.1.2.1.3 MySQL Versions Deprecation and Removal Policy in HeatWave Service

New versions and updates: HeatWave on AWS begins supporting new MySQL Server versions after they are released as Generally Available (GA). Customers are advised to regularly update their DB systems on both the Innovation or LTS/Bugfix tracks to the latest available version on HeatWave on AWS. Regular updates ensure access to the latest features, bug fixes, and security patches. To update the MySQL Server version of a DB system, see Upgrade MySQL Version.

Deprecation: Each MySQL version in the LTS/Bugfix track will be deprecated about one year after its GA date while each MySQL version in the Innovation track will be deprecated about three months after its GA date. When you are running a deprecated version of MySQL Server on your DB System, the MySQL version on the Details page of your DB System is marked with the Deprecated label. We strongly recommend updating and testing your DB system when its MySQL server version has been deprecated.

While you cannot choose a deprecated server version when creating a new DB System , you can restore the backup of a deprecated server version into a new DB System.

Removal: About three months after the deprecation date, the MySQL server version will become unavailable. Any DB system that is still running an unavailable version will be upgraded automatically in its next maintenance window. It is upgraded to the lowest version currently available in the same track on HeatWave on AWS. For example, when version 8.4.3 LTS becomes unavailable, it will be upgraded to 8.4.4 LTS, and when version 9.2.1 Innovation becomes unavailable, it will be upgraded to 9.2.2 Innovation.
