I'm trying to trace down a database upgrade bug and need to figure out a way of simulating market upgrades.

Answer 1

You can actually release into Play store as alpha and/or beta and test upgrade this way. It's best as it's a real upgrade from the store, nothing simulated.

EDIT

You can also try something like that: have a copy of the code of the previous version. Upload it to a test device. Then upload the new code, this will force a database update which you will be able to debug.
