Core Upgrades

The Laravel 5.3 Shift automates many of the upgrades listed in the Laravel Upgrade Guide, including:

  • Splitting out the new Authentication controllers.
  • Upgrading core Middleware and Providers to their Laravel 5.3 versions.
  • Detecting backward incompatibilities within your application code.
  • Adding new Laravel 5.3 configuration options.
  • Updating composer.json for Laravel 5.3.

Additional Upgrades

In addition to the Core Upgrades, the Laravel 5.3 Shift performs additional upgrades beyond those listed in the Laravel Upgrade Guide, including:

  • Applying your code style.
  • Modernizing PHP syntax, such as short arrays.
  • Streamlining the app folder structure by removing placeholders.
  • Creating the new routes folder structure.
  • Removing outdated framework components from your application.

Manual Upgrades

There are some upgrades the Laravel 5.3 Shift can not perform automatically. When Shift detects these it adds a detailed comment to the Pull Request to guide any additional steps you may need to do manually.

  • A few of the Query Builder methods changed in Laravel 5.3. Given the intricacy of query building, Shift can not automate this upgrade.
  • Laravel 5.3 includes several new default assets. Since your application likely customizes these assets, Shift does not change these files.
