The Migrate contrib project is great, many have used it before and it has brought some huge sites over to the Drupal side :)
There was a lot of talk about replacing the upgrade path with it during the years but the project only kicked off at DrupalCon Prague at 2013 September. Since then a team has formed, migrate has been rewritten with the new Drupal 8 APIs. It's more extensible than ever and yet it kept all the battle tested edge case handling.
This talk will introduce the audience to this initiative and show you how to write a migration in Drupal 8.
