Auth Controllers on Spark 2 and Laravel 5.3

I recently upgraded my laravel and spark installation using Laravel Shift from 5.2 and I have the following two notices

Laravel Shift AUTHOR
❌ Laravel 5.3 split the Auth/AuthController.php into the Auth/LoginController.php and the Auth/RegisterController.php. Since yours appears to be customized, I did not remove it. You should compare your Auth/AuthController.php with the newly added controllers and merge your changes accordingly.
❌ Laravel 5.3 renamed the Auth/PasswordController.php to Auth/ResetPasswordController.php. Since yours appears to be customized, I did not remove it. You should compare your Auth/PasswordController.php against the added Auth/ResetPasswordController.php and merge your changes accordingly.

I looked at the sample Spark application downloaded from the spark site and it has only two files namely the authController and the PasswordController. Am I supposed to delete the old files or delete the new ones.?
