MySQL 5.7 reaches end-of-life status in October 2023, requiring WordPress sites to upgrade to MySQL 8.0. Over 75% of WordPress sites currently run MySQL 5.7 or older, making this a widespread change affecting millions of websites.
Why This Matters
MySQL 5.7 support ends October 2023, after which no security patches or upgrades will be available. This creates increased vulnerability to security threats. WP Engine will upgrade all servers to version 8.0 before November 1st, 2023.
Major Benefits of MySQL 8.0
- Enhanced Security: OpenSSL improvements, new authentication methods, SQL Roles, and stronger password requirements
- Better Performance: InnoDB delivers superior Read/Write and IO-bound workload performance
- Improved Reliability: DDL statements become atomic and crash-safe
- Enhanced Observability: Better Performance Schema and error logging
Preparation Steps
Site owners should update all plugins and themes before migration, test compatibility using Local with MySQL 8.0, use staging environments to troubleshoot issues safely, and allow adequate time for fixes before the deadline. WP Engine provides compatibility testing tools and customer support for the transition.
