Making an Ipad app from an iphone app?

Hi, sorry if this is a stupid question, im pretty new to this. I've made an app for the iphone using CS5.5, but I now want to make it for the ipad. Is there a simple way to just make it a larger resolution to fit the ipad screen? I've tried making the stage larger then scaling up all my elements but then my code dosn't work properly as the elements are now in different places.

Is there a simple way to do this or do I just scale everything up and then redo the code with different coordinates?

I hope that makes sense, any help would be great, or any links

Thanks Ste

you will have to resize your graphics... thats it. although if you mean to run it on the ipad at iphone resolution and at 2 times.. then can use the scalestage Mode .SHOW_ALL method. refer to live docs.
