In Chapter 7, Migration Using the Migrate Module, we'll use another module to run migrations of content, called the Migrate module. We'll look at Migrate in more detail later in the book but for now you can review its project page on Drupal.org at http://drupal.org/project/migrate/. The current version of this module is 7.x-2.4.
Like the Feeds module, Migrate provides an interface in Drupal to import your content. Migrate also has integration with the Drush module, so you can run migrate commands using Drush in the command-line prompt.
