In the last tutorial we created a new site from scratch on Pantheon. What if you already have a site that you want to move to Pantheon though? In this tutorial we'll provide an overview of how to import your site into Pantheon. We'll discuss what the various parts of a site are that you need to work with, and some important points about what Pantheon expects. We'll also discuss the different methods you can use to import your site and the guidelines for which method to use, especially when working with large Drupal sites.
