App developed with AIR 1.5 (or Flex 3 sdk) export to Tablet

I have an enterpise app maked with Adobe AIR 1.5, developed with Flex 3 SDK and halo components (MX not Spark).

I want to export this app to a tablet for my client (this app is very easy to use in a touch screen). But i supose that i have to rewrite all app in Flex Hero SDK (and export with AIR 2.6) and its hard.

Anyone has export an app developed with Air 1.5 or Flex 3 SDK to a tablet of android, blackberry or IOS with AdobeAIR 2.5 or 2.6?

Perhaps it could run in a tablet of Windows 7 but this tablets seems realy poor...

Thanks guys!
