I am planning a different path:
- I got a new virtual server and am installing a fresh CS V4. To this, I will add all sensors that I couldn’t configure under V3 (due to incompatible CODECs).
- Originally, I installed “too many” gateways (5, since disabled 2, in facility <1 sq km!), so I will reprogram one of them to send data to the new CS V4.
- I will set SCADA to subscribe to sensors on CS V3 and CS V4.
- I will move over critical existing sensors to V4.
- Later, I will change batteries in all sensors currently configured in CS V3, disable V3, and join sensors anew to V4.
Will that work?
P.S. I am leery of changing passwords in postgres, in case this breaks V3 - I can’t afford to lose telemetry from existing sensors (in #4) as some have a vote in important alarms.
