Can I copy paste the raspberry pi SD card and use node red flow?

Hi,

I have to setup multiple R Pi for my project and mostly all flows are the same. can i copy and paste the new memory card with the data from my card of R pi in which my current flow is?

any recommendation?

Not really a node-red question tbf.

Firstly, copying files is not enough.

Google is your friend - search "clone raspberry pi sd card" there is a plethora of results.

Others may chime in about first setting which flow to load in setting.js as it's based on the host name of your device by default (search the forum or read the docs or simply look at your settings.js file)
