Writing a Custom Migration Plugin for Drupal 8

Among the many improvements in Drupal 8 is the inclusion of a refactored Migrate module to handle updating sites from Drupal 6 and Drupal 7 to Drupal 8. While Drupal 8 also includes a refactored Drupal-to-Drupal data migration module (renamed "Migrate Drupal"), only core migrations are included (including Link, Email, Telephone, and core CCK fields). For the vast majority of contributed modules (and all custom modules), migration plugins will have to be developed by module maintainers. 

This session will provide a demonstration of the basic concepts of writing a Migrate plugin as well as a walk-through of a sample plugin.
