So my wife has a Nexus 4. She just created a new Gmail address and wants to discontinue use of the old address that is currently tied to her phone and Play store with all her apps. I know how to add a new address to the phone, but I want to migrate her apps to the new address so her play store shows all her same apps but is associated with the new Gmail account. And then delete or deactivate her old gmail address. Hope this makes sense. How do I go about this?
