This is probably the last post in this series. I will try in this article to bring it all together. This will also be the most code heavy article. If you are new to migrate and Drupal-to-Drupal data migration, make sure you read and understand the first articles before preceding.

Source and target field have the same field name and type, but sometime you might want to fix a bad decisions made in the past and reorganize your architecture. Migrate call this field mappings. What ever reason you might have, you will need to share these ideas with Mirate. The basic format is like this:

$this->addFieldMapping('drupal7-field_name', 'drupal6-field_name')

More details are found in the official documentation at
