I have just updated from 5.0 to 5.1.20 (dev-master). There are many files in the app-folder wich (obviously!) not are updated since I could have made changes to those files.

So for instance the two Auth-controllers - They are currently still in 5.0-state. But I can see in the most recent code that they have changed.

I'm assuming there are many of these changes that I will not get when updating via composer. My question is now: Is this update good enough? Will I be missing some important code?

I have also tried to make a clean install (5.1.11) and then copy all my files to the new app. This also seems to work like a charm - But I'm just not sure which approach is the best?

Hi. First time poster. Just wanted to thank all of the above posters for the hints and suggestions allowing me to have a flawless upgrade.

With respect this is an older post, I recently released Laravel Shift - an automated upgrade tool for Laravel projects. There's a shift available for upgrading from Laravel 5.0 to Laravel 5.1. Hopefully it saves future readers time.
