Replace bricked doorbell with new one without deleting all video

A Ring firmware update to my v1 doorbell bricked it. I bought a new doorbell 3 and successfully set it up as "Front Door", which was also the name of the now-bricked device. After setting up the v3, I went to delete the original "Front Door" and the app tells me all the recorded video from that device will be deleted. There's nothing important there but I would rather keep the video from the old device. Is there a way to do that? Also, if I delete the old device will the subscription for cloud recording be automatically transferred to the new "Front Door"?
