Submitted by stygian - 3 years ago

This is a laravel command i wrote to handle the upgrade to 4.1 It covers everything in the upgrade doc except for handling missing method. It should be easily addable if you need it. Make sure to add the following to start/artisan.php Artisan::add(new UpgradeCommand); Artisan::resolve('UpgradeCommand'); Once finished, run the following php artisan auth:reminders-controller
