R – Convert Flex Builder 3 project to Flash Builder 4

If you have path names which will change depending on the enviroment then you will likely need to recompile for each environment since these will be compiled in the swf.

I typically use ANT scripts to handle my compile/deployment process when moving from development and production environments. This gives me the ability to dynamically change any path names during the compile. These build files can be integrated into Flex Builder making this process very easy once you have everything set up, and can be done with one click or scheduled.

Flash and Flex both use the same underlying rendering engine, just with different front-ends. Flash is better suited for making movies and animations. Flex is better for application development.
