In two projects, two Pi Zero 2 have proven to be not so stable and probably undersized, so I would like to switch to two Pi 4 with 4 GB.
The latest version of DietPi is installed as the OS in each case.
I would like to save myself a complete new setup, so here is my question:
Due to the certain similarity of the two Pi`s, is there possibly even the possibility that I can simply plug the SD card with the OS into the Pi 4 and the whole construct will work right away?
Or are major adjustments to be expected?
There are no “exotic” things installed, one is an ADS-B feeder and the other is ADS-B based on Wingbits.
Both have a HAT with 4x USB plugged in, but somehow this is not the optimal solution.
I would be very grateful for a few experience reports or tips.
It should work.
I propose additionally to do these steps:
Backup your system (e.g. with dietpi-backup or copying your SD card on a different system) or clone your SD card contents to another SD card (on a different system, e.g. via dd command)
Connect a monitor locally to the Pi 4 to be able to monitor the boot process (with its messages)
It worked without any problems.
Checked all updates again and updated the bootloader and the systems are running stable.
Certainly a little unconventional, but feasible. Thank you!
I wanted to say that it is certainly always better to reset the system when changing hardware. Since I was a bit “lazy”, I just tried to simply plug a system that was installed on a Pi Zero 2 into a Pi 4 and hope that it would work. It worked. Certainly helped by a certain similarity between the two Pi’s and of course the great stable DietPi!
