 Drupal 7 sites that are currently using Composer with Drupal 7 (e.g. with our [Drops 7 Composer upstream](https://github.com/pantheon-systems/drops-7-composer) or similar) are recommended to migrate away from Drupal 7 with Composer to make the most of Pantheon's Drupal 7 Long-Term Support. Contrib modules cannot be automatically updated in this model and updates would need to be applied manually.
