Preparing for the Migration

Before initiating the migration process, it’s crucial to take certain preparatory steps to ensure a smooth and successful transition. Here are some essential pre-migration tasks:

1. Backup Your Application
Before making any changes, create a comprehensive backup of your entire Laravel 7 application, including the database, configuration files, and custom code. This ensures that you can revert to the previous state in case any issues arise during the migration process.

2. Check Compatibility with Dependencies
Review the compatibility of your existing dependencies, packages, and third-party libraries with Laravel 8. Verify whether any of the packages you are currently using have released updates or patches that are compatible with Laravel 8. This will help prevent any compatibility issues that might arise post-upgrade.

3. Review Laravel Upgrade Documentation
Refer to the official Laravel upgrade documentation available on the Laravel website. Laravel provides detailed documentation for each version upgrade, outlining the specific changes and considerations required during the migration process. Familiarize yourself with the recommended best practices and guidelines before proceeding with the upgrade.
