Additional Steps

Update Configuration Files

Configuration files often receive updates in new Laravel versions. Compare your configuration files with the versions in the fresh Laravel installation and update them accordingly. This can be done using a diff tool or by manually reviewing the files.

Update Middleware

Check for any changes or deprecations in middleware. Ensure your custom middleware is updated to reflect these changes. Pay special attention to authentication and authorization middleware.

Review Routes & Controllers

Make sure your routes and controllers do not use any deprecated methods. Update any references to methods that have been changed or removed. Test all routes to ensure they function correctly.

Database Migrations and Seeders

Ensure your database migrations and seeders are compatible with the new Laravel version. Run migrations to verify they work correctly:

php artisan migrate

Deployment

After successfully upgrading and testing your application locally, you can deploy the changes to your production environment. Follow these steps:

  1. Backup Production Database: Always back up your production database before deploying new changes.
  2. Use Zero-Downtime Deployment: If possible, use a zero-downtime deployment strategy to minimize disruptions.
  3. Monitor Logs: Monitor your application logs for any errors or issues after deployment.
