Running Drupal 8 Data Migrations on Pantheon Through Drush
Editor's Note: The structure of Terminus commands have changed since this post was written. The example commands have been updated to reflect the current structure of terminus command:subcommand <site>.<env>. Also when this post was written, Drupal 8 was the newest version of Drupal and was a large technical departure from Drupal 7 (hence the need for robust migration processes described in this post).
