title: Is it possible to change keystore for an android application that is already deployed into Play Store being account administrator?
body: <p>We already have an android app deployed under Play. 
  Is it possible to change current keystore? Reason: currently we have a development team and this team will be discarded within 1 year. 
  I would like to know if it is possible to get 'current one' without asking them (we are owners of app - I have admin account in Play), replace this 'current one' and publish and new version of app, but using same package, same name.
  We intend users not to download new version, but to have it automatically updated.</p>
