The Upgrade database engine version feature in FPT Database Engine allows users to upgrade a MariaDB database engine from the current version to MariaDB 10.9. Upgrading enables you to take advantage of performance improvements, enhanced security, and new features in the higher version.
Log in to the FPT Cloud Portal and navigate to Database cluster list. Choose MariaDB cluster that you want to upgrade from your list of clusters. On the cluster’s Overview page, you can see the current version and an Upgrade icon next to it.

On the Overview page, click the Upgrade icon next to the version information. A dialog opens showing the current version and the target version(s) available.

Select the target version and enter the confirmation keyword in the input field. Select Upgrade to start the upgrade process.
During the operation, the database cluster status changes to "Updating". Do not attempt to connect or make changes while the update is in progress. The cluster will automatically restart as part of the upgrade.
After the upgrade completes successfully, the status returns to “Running”, and the database cluster is upgraded to the new version.
