Migrate Devel offers debugging tools to inspect source data, destination values, and entity IDs during Drupal migrations. It helps developers trace data through the migration pipeline directly in their terminal.
Debug your Drupal migrations with ease. Migrate Devel provides developer tools to inspect source data, destination values, and entity IDs as rows are processed—right in your terminal.
Features
- --migrate-debug – View source, destination, and saved entity IDs after each row is processed
- --migrate-debug-pre – Inspect source and destination values before processing begins
- Debug process plugin – Add inline debugging to any migration YAML to trace values through the pipeline
Part of the Migrate Ecosystem
Migrate Devel works seamlessly with Migrate Tools and Migrate Plus. Use it alongside your existing migration workflow—just add a flag to your Drush command and start debugging.
Usage
Add debug flags to your migrate commands:
drush migrate:import my_migration --migrate-debug
drush migrate:import my_migration --migrate-debug-pre
