This project contains Rector rules for Contao Open Source CMS upgrades.

!! WARNING !! this is currently experimental, use at your own risk

Install contao-rector via composer to your project:

composer require contao/contao-rector --dev

Level sets combine multiple changes for a specific Contao version, including dependencies like PHP, Symfony and Doctrine.

As an example, the ContaoLevelSetList::UP_TO_CONTAO_413 will upgrade your code to PHP 7.4 and Symfony 5.4, since Contao 4.13 does not support any lower versions.
