In this lesson we'll take a look at running migrations via drush rather than via the Migrate module's UI. We'll take a look at the commands provided by the Migrate module and talk about what they do. Then we'll practice running, rolling back, and otherwise interacting with migrations via drush commands. Throughout the lesson we'll learn about some of the functionality you get from running migrations via drush that are not provided by the UI, like the ability to specify a single record to migrate with the --idlist flag. Finally we'll learn about why in most cases drush is a better tool for running large data migrations because of the limitations imposed on the UI. Pay close attention to this lesson since throughout the remainder of this series we'll be running all of our migrations via drush.
