As promised at the Developer Summit, here is the link to my presentation, a short write up of tips and tricks and the source code for the migrated LiveLayerWidget. The LiveLayerWidget.mxml has comments in the code about all the changes so you can use it as a step by step process for you migration as well. As I mention in the word document "If you REALLY get stuck after REALLY trying to understand and figure it out yourself and have a SPECIFIC question about the migration, then post a question here".
