laravel new version are more complex not simple as before I like laravel but not like frequent updating new version their UI depend on vue.js intentionally

Solution

According to my experience I upgraded from laravel 7.2 to laravel 8 Check upgrade

You have to check all dependencies required in version 8. As I remembered in version 5 routes are in app folder but in new version routes sre in root folder so you will face many problem. There is more different b/w laravel8 into laravel5. Even folder structure are different so.

If you developed your projects then develop from scratch.

1. Download a fresh laravel without any package
2. check dependencies and all packages mentioned in your old projects composer.json and composer.lock . Don't forget to check package.json if exists
3. Now mention all the packages (with upgraded version by comparing using link ) in your new projects composer.json file .
4. composer update

Now you have to check if your projects can run in upgraded version. 5. Copy vendor folder composer.json file and composer.lock and bootstrap folder 6. Now php artisan serve 7. If your projects running smoothly then go further 8. Copy your routes.php from app folder of old project to routes/web.php new projects 9. Copy all view from old projects to new projects 10. Copy all your models and all your controllers 11. Now add "files" :["app/Http/helpers/helpers.php"] lines in composer.json 12.now composer dump-autoload Then run your server if runs well then your code can work on version 8 environment.

don't forgot to check all folder from app and config folder if you find any extra file just copt it p.

Now here is an problem with your admin panel or login panel if you have otp or another extra feature do it from scratch.

here is no commands to upgrade from version 5 to version 8.
