Sorry guys, I realize I screwed the pooch on that one. Yes, they are at least all still accessible in the XML, but we did not build a migration for them to the new playlist features. That would be pretty difficult because the method and logic behind the two are rather different. Depending on how many complaints we get, I may go back and add a migration feature, but honestly I'd rather focus on new features like nested filters. That said, my apologies for the oversight.
