+Migrate Chado
+-------------
+
+This module is a collection of destination plugins to import biological data to a Chado database using Migrate. The Migrate module provides a flexible framework for migrating content into Drupal from other sources (e.g., when converting a web site to Drupal). Content is imported and rolled back using a bundled web interface (Migrate UI module) or included Drush commands (strongly recommended).
