Not sure if this will help, but if you upgrade your Flex 3 app to be a Flex 4 app, you can maintain the look of your legacy app by setting set the theme to be Spark and Halo. Then moving forward, you can use spark with the new spark theme while maintaining the look of your legacy app.
So in your flex-config.xml, you would set it to something like: <!-- List of CSS or SWC files to apply as a theme. --> <theme> <!-- The Flex 4 default theme is Spark. --> <filename>themes/Halo/halo.swc</filename> <filename>themes/Spark/spark.css</filename> </theme> Hope that helps. Good luck.
