Migrations Laravel Package
doctrine/migrations
Doctrine Migrations manages database schema changes via versioned migrations for PHP projects. Generate, run, and track migration scripts, integrate with Doctrine DBAL/ORM, and safely evolve schemas across environments with robust CLI tooling and documentation.

Frequently asked questions about Migrations
- Can Doctrine Migrations replace Laravel’s native `php artisan migrate` for managing database schema changes?
- Yes, but with trade-offs. Doctrine Migrations uses its own format (YAML/XML/PHP) instead of Laravel’s PHP class-based migrations. For new projects or complex multi-database setups, it’s a powerful alternative. Existing Laravel migrations can coexist if structured carefully, but full replacement requires migration file conversion or parallel adoption.
- How do I install and configure Doctrine Migrations in a Laravel project?
- Install via Composer: `composer require doctrine/migrations`. Register the configuration in a Laravel service provider (e.g., `AppServiceProvider`) by binding the Doctrine `ConnectionConfiguration` to your database connection. Use the CLI (`doctrine:migrations:execute`) or programmatic API to run migrations. Full setup details are in the [official documentation](https://www.doctrine-project.org/projects/migrations.html).
- Does Doctrine Migrations support Laravel’s Eloquent ORM and database connections?
- Yes, it integrates seamlessly with Doctrine DBAL, which Laravel already uses under the hood for database interactions. You can leverage Eloquent models and Laravel’s connection configuration (e.g., `DB::connection()`) to manage migrations. This ensures compatibility with Laravel’s primary data access layer.
- What Laravel versions are compatible with Doctrine Migrations?
- Doctrine Migrations works with Laravel 5.5+ and PHP 7.2+. It relies on Doctrine DBAL, which is already bundled with Laravel. Check the [Doctrine Migrations documentation](https://www.doctrine-project.org/projects/migrations.html) for version-specific requirements, but it’s generally backward-compatible with modern Laravel releases.
- How do I test Doctrine Migrations in a CI/CD pipeline?
- Use Laravel’s testing tools (e.g., `php artisan migrate:fresh --env=testing`) alongside Doctrine’s CLI commands in your CI pipeline. Test migrations in isolation by spinning up temporary databases (e.g., SQLite for unit tests). Verify rollbacks with `doctrine:migrations:execute --down` and assert schema states using DBAL’s schema comparison tools.
- Can I use Doctrine Migrations alongside Laravel Forge or Envoyer for deployments?
- Yes, Doctrine Migrations integrates with deployment tools via CLI hooks. Add `doctrine:migrations:execute` to your Forge/Envoyer deployment scripts or use Laravel’s `post-deploy` hooks. For zero-downtime deployments, run migrations in a separate step or use Doctrine’s `--dry-run` flag to preview changes before execution.
- What are the performance implications of using Doctrine Migrations vs. Laravel’s native migrations?
- Doctrine Migrations introduces minimal overhead due to DBAL’s abstraction layer, but benchmarks show negligible differences in most cases. For large-scale projects, test both approaches in staging. Laravel’s native migrations may offer slight speed advantages for simple schemas, but Doctrine Migrations excels in complex, multi-database, or cross-environment scenarios.
- How do I handle rollbacks or fix failed migrations with Doctrine Migrations?
- Doctrine Migrations supports rollbacks via `doctrine:migrations:execute --down`. For complex failures (e.g., foreign key constraints), manually create a new migration to correct the schema. Use `--dry-run` to preview changes before execution. Always test rollbacks in a staging environment to avoid production issues.
- Are there alternatives to Doctrine Migrations for Laravel database versioning?
- Laravel’s native migrations (`php artisan migrate`) are the default choice for simplicity. For advanced use cases, consider **Flysystem Migrations** (for file-based schemas) or **Spatie’s Laravel Migrations Generator** (for scaffolding). Doctrine Migrations stands out for its cross-platform support (YAML/XML/PHP formats) and integration with Doctrine DBAL/ORM.
- How do I version-control Doctrine Migrations alongside Laravel code?
- Store migration files (e.g., in `database/migrations/doctrine`) in Git alongside your Laravel code. Use Git tags to mark migration versions (e.g., `v1.0.0`) and correlate them with releases. For teams, enforce a workflow where migrations are reviewed and tested like application code to prevent schema drift.
