Changing an app's capabilities

Hello everyone. I'm in an interesting situation where I'm writing a new version of an app from the ground up because the previous (old buggy) app was written using a technology that's out of date and no-one here understands.

Because the app has a local database we want to load into the new app we are keeping the original bundle id. The theory being that the new app overwrite's the old app on a user's device and reads its data.

The problem I have is that it appears that the old app had location updates turned on and was (possibly) consuming battery as a result. In the new app I don't think we need this capability any more and I also want to add the "Background Fetch" or "Background Processing" capability to schedule so local notifications.

My question is can I change the capabilities of an update to an app in the App Store, or am I restricted to the capabilities of the original app?
