Apologies in advance for this off topic question, but I'm sure someone out there has had a similar issue and solved it.
My RPi4 ran both Weewx and a program to monitor my solar panels. The Pi died and I've finally managed to get a replacement. Unfortunately when I transfer the SSD card to the new Pi4 I get the messages “start4x.elf not compatible” and “this board requires newer software”. It appears that the replacement RPi requires new firmware. I tried running update the firmware, use sudo rpi-eeprom-update -d -a using an other 'old' RPi4 but I still get the same error. I could of course start again with a fresh OS installation. Weewx is not the issue as it's relatively straightforward to retrieve my history, but it's the solar panel monitoring program that stops me doing this as I would lose my entire history - I cannot figure out where it saves its history to as it appears to save data in hidden folders. My question is, is there a way update my SSD card to allow it to run on the newer RPI4 without a full re-install?
