If I create a new account, will it erase previously stored videos on ring?

My landlord setup the ring doorbell and has her own account that we have been using, however she does not have a subcription. If I were to setup my own account and link the doorbell, will I have access to previously cached videos? Or will all of that get deleted? I wish there was a way to transfer owership between accounts instead of just User and Guest. Almost like adding someone as an admin.
