Using the Migrate Module for Fewer Headaches when Relaunching a Site
Video by Variant Studios
The migrate module has been overhauled by Cyrve into a version 2.x branch which has been used at Examiner.com, Martha Stewart Living Omnimedia, and NREL to move data from various other sources to Drupal 6 and 7.
I'm going to go into how to use this version of the migrate module, what things it does well, what things you may need to fudge, and the sorts of things that I've discovered while working with it on a large project.
People attending will probably want to be developers, and there's going to be a fair bit of code involved, and should be familiar with both object oriented programming and drush.
