Note: this information applies to the Drupal 8 migration system - it should be moved out of the documentation for the Drupal 7 migrate module.

This is an example of a customized mapping migration of Drupal 6 content to a new
Drupal 8 instance. The new Drupal 8 instance has its own bundles and field instances already built out.

Example customized mapping migration module

This module demonstrates the following Drupal 8 migration techniques:

• Migration of translated Drupal 6 nodes.
• Custom mappings of roles.
• Converting node references to term references.
