Can I change the gmail account associated with google play store? When I got my android phone I had a gmail account, gmail-1, but have now created another account, gmail-2. Is it possible to transfer my play store info (i.e. app download history) from gmail-1 to gmail-2 and set gmail-2 as my primary email?
Google has this to say on transferring data between accounts.

It lists certain types of data that CAN be transferred and certain types of data that CAN NOT be transferred. Unfortunately Google Play Apps falls into the NOT category.

It's conveniently titled Moving Product Data.
