You can upgrade to a newer version of MySQL on the connected Linux server on which Unified Manager is installed to obtain fixes for security vulnerabilities. For any minor upgrade, the base version of MySQL must be 8.0.20 or later. If the installed version of MySQL on your system is earlier than 8.0.20, the Unified Manager 9.7 upgrade process automatically upgrades MySQL to 8.0.20. You must not run a standalone upgrade of MySQL from an earlier version to 8.0.20.
You can upgrade the base version of MySQL 8.0.20 to later versions for only minor updates.
