How best to replace base station

I have received a replacement base station from ring. The ring representative told me on the phone that I did not have to remove all my sensors and that she would email me instructions on how to replace the base station. The email contained many links on how to install a brand new system, how to add various new sensors, how to change my password, ..., but nothing about replacing an existing base station. Any advice on best to proceed? Lacking advice to the contrary, I'm guess... 1. Use the ring app to remove all my existing sensors. 2. Use the ring app to deregister the base station 3. Remove all the batteries from my existing sensors. 4. Follow the instructions for installing a brand new system. Thoughts?
