Module Link: http://drupal.org/project/migrate

• Who: Only VERY technical users - You need to understand how the Table Wizard module works and not get frustrated too easily.
• What: The Migrate module allows you pull information from non-Drupal database tables and make them into Nodes, Users, Comments, etc.
• When: Use this module when you need to pull data from a table that isn't related to Drupal AND you want to get that data into a Drupal native table.
• Where: You can find this module in the admin back end under content management.
• Why: Writing import modules for Drupal is not fun and takes a lot of time. If you already have your information saved in your database this makes it easy-ish to import.
