Any help will be appreciated. Thanks in advance

Maybe you can provide some more information for the people willing to help; what are the steps to reproduce? Which steps have you already took compared to the Upgrading Guide? Etc.

In my opinion it's probably not a framework issue (plus 5.3 is already older) and I would not create this issue on the framework, but post it on something like stackoverflow. ✌🏽

OK teuunn, Thanks for the reply. Can you please guide me that what kind of changes do I have to make for custom AuthController in laravel version 5.3? I mean I haven't used new Authentication process with 4 new controllers.

@piyush-azova my advice is to change your custom auth to Laravel's auth. In that case you can also upgrade easier (in the future). Maybe you also want to take a look at Laravel Shift
