How to Resolve Manually
This Config Rule verifies if RDS DB Instances are deployed using the latest supported engine version and are not eligible for AWS extended support fees. The rule will be flagged as non-compliant if an instance is found running an unsupported version. You can read more about RDS Extended Support here.
You can resolve this through several methods, but all of them will involve some sort of downtime. So choose the proper one according to the uptime needs of the involved instance.
In case that your current RDS instance supports it, you can modify the DB engine version from the instance properties screen from within the RDS Console. Notice that once a DB instance has been upgraded, you cannot convert it back to the previous version. Always make sure you have tested both your database and your application with the new version before performing any action.
Another method that AWS recommends is to use a blue/green deployment. This basically copies a production database environment to a separate, synchronized staging environment that you can test before promoting this instance as the productive one. Check the documentation linked here.
