Best process for replacing ESP32 components in ESPHome?

ESPHome

Hi, there!

I have an ESP32 which I will replace with a new one.
The reason is that it controls one power relay today, and I need to extend it to control two relays.
For testing purposes I was thinking replacing the existing components with an entire new set of components, including the new 2x relay.

How would you suggest I go about this?
I will obviously copy the yaml over, but will I need to delete the existing ESPHome entry, or can I just add a new switch (to control the second relay) to the existing yaml and then flash a new ESP32 with the new binary?

Any tips for what GPIO is the best to use to control the relays?

I’ve had best results totally removing the affected device from the ha integrations screen and then re adding it.
