Switch from Pi Zero 2 to Pi 4

Troubleshooting
1

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:

  1. 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)
  2. Connect a monitor locally to the Pi 4 to be able to monitor the boot process (with its messages)
  3. Plug the SD card to the Pi 4
  4. Cross your fingers and switch on :slight_smile:

Well then, I’ll try my luck following the tips.:vulcan_salute:
