I have existing flash 8 AS2 work that I want to update to Flash 10. Can I update only those elements i need to be Flash 10 and load them in to the Flash 8 movie as an external swf and pass variables and call methods? Is this a good option and what are the issues to be aware of? Eg will a user with player lower than 10 be able to load the flash 8 movie and then find that it breaks because the flash 10 wont load or will the player realise that there is flash 10 content and inform the user that they need to upgrade their player?

thanks
