I had RPI zero w running a Blynk local server. And from past two days it shuts off automatically and again i have to manually turn it back on.
I guess the hardware is failing.
Now i am thinking to setup a new server on a RPI 3 which i have it lying around from quite a few months. But there are few devices which are connected to this RPI zero w server and i am not able to reach them to change the auth token.(all set inside a enclosure)
So i am thinking of just transferring the existing server files to the new server. Is this possible? This way i can leave the ESP’s with the existing auth tokens…
I cannot fiddle around because i have only one SD card(in the RPI 0 W), and once i flash it all the files will be gone. So i am here to ask if this really possible ?? (I will be re-using the same SD card on RPI3)
And to be on the safer side can i create a snapshot of the Blynk server every week/month so ? So that if anything breaks, i can simply restore the files and get it up and running ?
