1. I've just started working on Flex 3. I would like to know how easy / difficult is it to learn Flex 4 while or after learning Flex 3?
2. Does the book cover migration from Flex 3 to 4?

Yes, the book does cover migration, and it makes the process of moving from 3 to 4 fairly easy since we were all in the process of transitioning while we were writing it, so there are a lot of "migration tips" that we included as we encountered related issues.
