Recently I needed to do a migration from the Simple Machines Forum (SMF) to the Drupal Native Forum. I think most people by this point have heard of Drupal, and if you're reading this, chances are you're in a similar situation. If you want to migrate from SMF to Drupal, there is no direct route beyond writing your own Migration software from scratch in PHP. In this project I'm migrating from a Bridged Joomla and SMF site that has roughly 16,000 posts and about 1100 users.
