I was able to upgrade Mobian to Bookworm without reinstallation. Just follow the instruction here.
I was doing the upgrade via a wired LAN connection over SSH and inside screen session. This may be important as WiFi connection and screen unlock PIN stopped working during the upgrade process. Maybe disabling screen lock and doing the upgrade on the device screen is also possible.
After upgrade was complete and after first reboot screen unlock still was not working. I've rebooted again and the issue fixed itself as per this note.
I also had to play a bit with turning on/off airplane mode and rebooting few times to make both cell connection and WiFi work.
