This skill provides a comprehensive framework for migrating TYPO3 extensions to modern LTS versions by orchestrating powerful tools like Rector, Fractor, and PHPStan. It guides AI agents through a rigorous planning phase, updates composer dependencies, and automates code refactoring for deprecated APIs, FlexForms, TypoScript, and Fluid templates. Designed for developers maintaining legacy TYPO3 codebases, it ensures high-quality migrations through static analysis and automated testing while providing quick access to version-specific changelogs and implementation patterns.
