Tophermiller We have made great experiences converting our codebase from AS3 to Haxe to convert Flash to HTML5. The library OpenFL mirrors the Flash API so the code changes are kept to a minimum. Haxe and OpenFL also allow to export to .swf, so you can utilize the Flash Player or Air builds as long as you want, but you can also work on an HTML5 output. Haxe and AS3 are very similar and there are tools that help with the automated conversion. Here are more details about our conversion, in case you are interested: Releasing a preview of our HTML5 clients – Haxe + Air = ❤️ The conversion takes some time of course, but if your company is making considerable revenue with the Flash product, they might want to invest a little more.
