Sylius regularly releases new versions according to our Release Cycle. Each minor release comes with an UPGRADE.md file, which is meant to help in the upgrading process.

  1. Update the Sylius library version constraint by modifying the ``composer.json`` file:

        "require": {
            "sylius/sylius": "^1.7"
  2. Upgrade dependencies by running a Composer command:

    composer update sylius/sylius --with-all-dependencies

    If this does not help, it is a matter of debugging the conflicting versions and working out how your composer.json should look after the upgrade. You can check what version of Sylius is installed by running composer show sylius/sylius command.

  3. Follow the instructions found in the ``UPGRADE.md`` file for a given minor release.
