Enterprise Magento Upgrade
2.4.3 to 2.4.8. Multi-region rollout. 30+ modules audited. Zero downtime.
Challenge
An enterprise retailer running Magento Commerce 2.4.3 across EMEA and USA store views needed a major version upgrade to 2.4.8 to resolve end-of-life security concerns, gain PHP 8.4 compatibility, and unlock performance improvements. The platform had 30+ third-party modules, custom integrations, regional payment gateways, and a Hyva theme — all of which needed compatibility auditing before a single line of code was changed.
Approach
- Full pre-upgrade audit: module compatibility matrix across all 30+ vendor and custom modules, identifying breaking changes, deprecated APIs, and version constraints
- Phased upgrade execution: Composer dependency resolution, database schema migrations, and Hyva theme compatibility updates with zero data loss
- Static analysis with PHPStan and PHP compatibility scanning to catch type errors and deprecated function usage before deployment
- Delivered a comprehensive documentation package covering the upgrade path, module status, resolved conflicts, and post-upgrade verification steps
