The devices will always talk to the same endpoint, regardless of the backend configuration and the number of backends. If you are adding a new backend or integration to your system you can route the data to the new system without having to reconfigure the devices itself.
The same applies if you are replacing the SIM card or hardware itself for a device; reconfigure the device in Span and you backend systems will continue to process the data.
