How do you handle custom migrations in Drupal?

Answer: To handle custom migrations in Drupal, you typically use the Migrate module, which allows you to define migration configurations in YAML files. Here’s a brief overview of the process:

1. Create Migration Configuration: Define your migration in a custom module by creating a YAML file under the `config/install` directory. Specify source, destination, and field mapping.

2. Implement Source Plugin: If necessary, implement a custom source plugin to pull data from your specific data source.

3. Use Destination Plugins: Choose or create destination plugins to define where the data will go in Drupal.

4. Run Migrations: Use Drush commands (e.g., `drush migrate:import [migration_id]`) to execute the migration.

5. Handle Rollbacks: Implement rollback functionality using commands like `drush migrate:rollback [migration_id]` to revert migrations if needed.

Customize the migration process through hooks or additional configuration as required for your project.
