Here's a general outline of the steps you might follow when upgrading Laravel:
Read the Upgrade Guide: Start by checking if Laravel's official documentation has released an upgrade guide for the specific version you want to upgrade to. Laravel's documentation is usually very comprehensive, and it will provide you with step-by-step instructions on how to upgrade your application.
Check Compatibility: Before attempting an upgrade, ensure that your application's dependencies and packages are compatible with the new Laravel version. Some packages or custom code may need adjustments to work with the new version.
Backup Your Application: Always create a backup of your current application code, database, and any configuration files before proceeding with the upgrade. This ensures that you can roll back to the previous version in case something goes wrong.
Upgrade Dependencies: Update your application's composer.json file to require the new version of Laravel. Then, run composer update to update your dependencies to the latest versions compatible with Laravel 10.
Update Configuration: Check the config directory for any changes in configuration files. Laravel often introduces new configuration options or changes to existing ones. Make sure your configuration is up-to-date.
Update Routes and Middleware: Check your routes and middleware. There may be changes in the way routes or middleware are defined or used in the new version.
Check for Deprecated Features: Laravel may deprecate certain features between major versions. Review the deprecation notices in the documentation and update your code accordingly.
Test Your Application: After making the necessary code changes, thoroughly test your application to ensure that it works as expected. Pay special attention to any areas of your application that interact with Laravel's core components.
Update Dependencies and Packages: Laravel upgrades may require updates to third-party packages and libraries used in your application. Make sure all your dependencies are compatible with the new Laravel version.
Deploy Gradually: If your application is in production, consider deploying the upgrade in a staging environment first to catch any issues before rolling it out to production.
Monitor for Issues: After deploying to production, monitor your application closely for any issues, errors, or performance problems. Be prepared to address them quickly.
