android-market

Without additional context, the answer is "no", I think. Here is the context. I want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version. I want to use the same code base and just switch a setting to build the premium version. Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available.

I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?
