Downgrade Laravel 5.3 to 5.2

I've just downgrade Lv 53 to 52. Here some notes:

- update composer.json: laravel 5.3 to 5.2
+ php 5.6.? to 5.5.9
+ remove passport and related if use it. (OAuth json build in lv53 instead of JWT)
+ Copy default file in App\Http\MiddleWare and/or  \Provider.
+ Update User.php model.
+ Update app, remove Notificable(?), and other class (don't remember)
- Merge all route 5.3 web.php, api.php console.php to routes.php in App\Http\ in Lv 5.2

=> run composer update.
If error, trace to class and config/ to update.


I'm too lazy to downgrade Xampp to php5.5 so still run on php 5.6 just fine.
I install 2 version of Xampp on diff location and cant start it dependence. Still not try to run on Xampp php5.5.

On Windows server I've try to install 2 version of xampp but no luck because may be some service of xampp can not use for both version. So I have to unistall old xampp and clean be4 install new version.

I will write some note how to remove old Xampp services and change PATH to new xamp version.
Windows server's suck. We have to restart server to update PATH and others ...
