I have a running OpenHabian on my Raspberry Pi 1 and I’ve just realized that I can’t just move the SD card to 3B+ and expect it to work. I read about replacing start.elf to the latest one from raspbian, but it didn’t seem to help.
Is there a way to move the existing installation without having to start from scratch?
Thanks for suggestions. Actually, I did more research after posting. I did Rasbian upgrade from Jessie to Stretch following online suggestions how to do it. It went fairly smooth and now I have openhabian with Stretch running on my RPi 3B+
Yes, it took ca. 12 hours to update on RPi 1… But setting it all up took me way longer…
