Convert Actionscript 2 project to Actionscript 3

I have a AS2 project which works perfectly drawing in XML into a bunch of arrays, and showing and displaying external swfs when the user clicks the next button. Unfortunatley it was all designed in AS2 and to use the latest version of Captivate, it needs to be AS3. Althought I do understand AS3, I am having difficulty to translate the existing AS2 code. I can provide the existing swf to see the functionality, however it is just converting around 1500 lines of code to AS3. Contact me if you have any more information. Cheers.
