🔧 Upgrading MySQL Software: The ShipHero Approach

Database upgrades aren’t optional—they’re mission-critical. Older MySQL versions eventually reach end-of-support, meaning no more security patches or bug fixes. Running unsupported versions exposes our systems, our customers, and our business to security vulnerabilities and operational risks.

In 2024, we migrated our Aurora MySQL fleet from 5.7 to 8.0. This approach—automated, observable, and fully reversible—is now the ShipHero standard for every upgrade we perform, applied consistently across all our services and databases. It is used for every upgrade, from minor patches to major versions.
