RDS global clusters should run on a supported Aurora MySQL version

Description

Amazon Aurora MySQL global clusters should run on a supported engine version. Running unsupported Aurora MySQL versions exposes the global database to known security vulnerabilities that are no longer patched by AWS and may incur Amazon RDS Extended Support charges. Long-term support (LTS) releases remain compliant even when below the minimum version.

Remediation

To upgrade the engine version of an Aurora MySQL global cluster, follow the steps in Upgrading the Amazon Aurora MySQL DB engine.
