Major version upgrades for RDS for MariaDB

Major version upgrades can contain database changes that are not backward-compatible with existing applications. As a result, Amazon RDS doesn't apply major version upgrades automatically. You must manually modify your DB instance. We recommend that you thoroughly test any upgrade before applying it to your production instances.

Amazon RDS supports the following in-place upgrades for major versions of the MariaDB database engine:

  • Any MariaDB version to MariaDB 11.4

  • Any MariaDB version to MariaDB 10.11

  • Any MariaDB version to MariaDB 10.6

  • MariaDB 10.4 to MariaDB 10.5

If you are using a custom parameter group, and you perform a major version upgrade, you must specify either a default parameter group for the new DB engine version or create your own custom parameter group for the new DB engine version. Associating the new parameter group with the DB instance requires a customer-initiated database reboot after the upgrade completes. The instance's parameter group status will show pending-reboot if the instance needs to be rebooted to apply the parameter group changes. An instance's parameter group status can be viewed in the AWS Management Console or by running a "describe" call such as describe-db-instances.
