app vs www

Hey,
I currently have all my destination url’s/landing pages for PPC in google as http://app. I have quality scores and a good amount of history (ctr %, conversion history) indexed into google for these ads. I am thinking about changing my domain for all my ads from http://app. to http://www. as it would significantly increase my quality score but I would lose all my history retained with my keywords and ads. Is there a way to change my domains to http://www and not have everything refreshed? Thanks
