Transition Between External SWF

I have recently made the switch to Actionscript 3.0. I am slowly, but getting the hang on of it. I am re designing my portfolio in AS3.0 as a form a practice. On my previous portfolio I transitioned through external SWF’s using this method posted on Kirupa.

It worked great and was not hard to do at all. After about 5 days of looking on the web for a tutorial that shows how to transition through SWF’s using AS3.0 I still can not find any. Can anyone point me in the right direction whether it be tips, or full tutorials on how to accomplish my goal?

Thanks,
