I've spent a fair bit of time this week helping people who are trying to get their Flex 1.5 apps working in Flex 2. Some of those apps worked with only a tiny tweak here and there and others will pretty much require a total rewrite. What I'm finding is that there is enough difference between what you *can* do in AS 2 and what you *must* do in AS 3 that it's probably better to learn AS 3 and use as much of those principles and syntax as possible when creating AS 2 apps. That way your AS 2 apps will still work and you'll have minimum pain if and when you port them to AS 3.
FWIW, the apps that were easiest to convert were what I would consider well designed in an OO sense. Each file did one thing and only one thing. Each file was well decoupled from other files and well encapsulated. I'd like to think that's just because OO is a good thing, but I suspect that it's got as much to do with the fact that AS 3 is stricter about OO concepts than AS 2 was.
