Raspberry Pi Forums

Simple question (no question ever turns out so, but I live in hope)

If I build a system on a Pi3 B on Ubuntu 20.04 including all applications, docker etc - can I simply take the SD card out of the Pi3, pop it in a Pi4 and expect it to boot up and run correctly?

I have a niggling suspicion that the boot partition may differ due to firmware. If that is so - could I create a new SD card from the Pi4 Ubuntu download image and the overwrite the mmcblkp02 partition with an rsync from the Pi3 to make the Pi4 root system identical to what is working on the 3?

I doubt the firmware will be an issue, it certainly isn't for Raspbian Buster, but I don't know about Ubuntu.

This question would be better off asked in the Ubuntu section of the forums. I'll ask for it to be moved there.

OK thanks.

The trigger for the suspicion was that the Ubuntu site downloads have distinct links for 3 & 4 which I dangerously assumed meant that *something* differs in the images. Having looked at the URL behind the links they seem identical so maybe it's not an issue.
