DB System Upgrades
HeatWave Service supports automatic and manual upgrades.
- Automatic upgrades:
- Updates within the same version, such as 8.0.33-u1, are applied automatically during the maintenance window that you define on the DB system. The update versions contain critical patches such as security and stability fixes.
- A deprecated version becomes unavailable about three months after the deprecation date. See MySQL Versions Deprecation and Removal Policy in HeatWave Service. Any DB system that is running an unavailable version will be upgraded automatically during its next maintenance window. It is upgraded to the lowest version currently available in the same series. For example, when version 8.0.31 becomes unavailable, it will be upgraded to 8.0.32 and when version 8.1.0 becomes unavailable, it is upgraded to 8.2.0.
- Manual upgrades: You can manually upgrade the version using the
Console or the CLI. See Manually Upgrading a DB System.
Note
It is recommended to perform a full backup before upgrading the DB system.
Manually Upgrading a DB System
Use the Console or CLI to manually upgrade a DB system to a higher version. You can upgrade to the same version (to get the latest security and critical fixes), but you cannot downgrade to an earlier version.
Note
If you want to perform a major version upgrade such as MySQL 8.0 to MySQL 8.4, you should check the changes before upgrading. See Major Version Upgrade.
