Rector for TYPO3

Rector for TYPO3 was created to help developers upgrade their TYPO3 installations and ensure their extensions support the latest versions of PHP and TYPO3. Rector scans your code base and replaces any deprecated functions with an appropriate replacement. Rector can also help ensure better code quality by means of automated refactoring.

Rector can run as a standalone package or it can be integrated with your CI pipeline.

EXT: Core Upgrader (v2)

The TYPO3 extension was initially developed as EXT:core-upgrader <https://github.com/IchHabRecht/core_upgrader> (Composer package ichhabrecht/core-upgrader, compatible up to TYPO3 v10) and has been forked as EXT:core-upgraderv2 <https://github.com/WapplerSystems/core_upgrader> (Composer package wapplersystems/core-upgrader, compatible up to TYPO3 v12).

The extension allows to perform multiple TYPO3 Core version upgrades in one step by offering the older upgrade wizards.

Another way to perform (and test/verify) upgrades of multiple TYPO3 versions in one go is outlined in a blog article "Automatic TYPO3 Updates Across Several Major Versions With DDEV <https://typo3.org/article/automatic-typo3-updates-across-several-major-versions-with-ddev>.
