Question about including HR Renewal in a EhP7 update

Good afternoon - We are planning to update to EhP7 (currently on EhP6). This will mostly be a technical update, but we would like to be positioned to activate HR Renewal components at a later date. If we include the HR Renewal add-on into the EhP7 update, will the classic HR functions continue to look and feel as they do today, with any HR Renewal changes needing to be activated in the Switch Framework?

Thanks for your help!
