The Pi 3 is a 32 bits cpu, the Pi 4 a 64 bits one. So keep your 32 card for the pI 3 and install a freh, complete new OS on the Pi 4, including python3 and all you need for weewx, without tuchung weewx. Then when your Pi 4 is rolling, you can probably copy the full weewx from the 32 card at

I don't think you can do that. A Pi3 and a Pi4 are significantly different from a hardware standpoint. The SD card would contain configuration information about when the O/S was installed and configured. I suspect you need to download and reinstall a fresh copy of the O/S, configure it as per y
