Can I test a migration before applying it to the database?

Yes, you can use the '--dry-run' flag with the migrate command to see the SQL that would be executed without actually modifying the database schema.

How do I generate a new migration file?

After modifying your Symfony entities, use the 'bin/console make:migration' command to automatically generate a PHP migration file containing the necessary SQL changes.

How do I handle migrations in a CI/CD pipeline?

Integrate 'bin/console doctrine:migrations:migrate --no-interaction --allow-no-migration' into your deployment script to automate database updates safely during deployment.

What is the safest way to rollback a migration?

You can use 'bin/console doctrine:migrations:migrate prev' to rollback to the immediately preceding version, or specify a specific version ID to return to a known stable state.
