I am running OH2.5.5 on RPI3 with a very old install of openhabian (Jessie) on a 4GB SD card. Making a clone of the card and run it on a test RPI3, I have made several attempts to do an in-place upgrade, but never succeeded. OS upgrade failed due to disk space issues. Alternative approach by copying the image to a larger card, resize the partition and then attempt a new OS upgrade also failed.
I now took a different approach
take a backup of my running OH with openhab-cli
do a fresh install of openhabian on a new RPI4
downgrade the new install to OH2.5.12 with openhab-cli
restore the backup.
upgrade to OH by using option 03 in openhabian-config
The OH2 instance on the new RPI4 seemed healthy. All things and items were present, rules were executing etc. After upgrade to OH3, only the things and items that were defined in text files, were there. All things and items I created via Paper UI in my old install, were not there any more.
Questions:
Is my migration plan as explained above supposed to work?
Is there a way to find out why the things/items that are in my jsondb in OH2 don’t show in OH3 after upgrade?
Is there another migration approach that has a bigger chance of success?
Thanks, I hadn’t thought about that one. After flashing openhabian-pi-raspios32-v1.6.5.img to SD card, I made this edit:
# repo and branch to clone from
repositoryurl=https://github.com/openhab/openhabian
clonebranch=stable
Still, this is installing OH3.
This is – I think – the relevant section in first-boot.log, where it mentions that OH3 will be installed

First install failed, but I forgot to keep the first_boot.log. Sorry for that. I then flashed the image all over, enabled debug logging. OH2 seems to install properly and I can access the UI.
In the debug log I see some errors that you might find interesting:
some are related to file paths openhab2 vs openhab
some are related to the frontail/npm issue that has been reported elsewhere on this forum and not really relevant.
You are using the wrong image. You have begun using a testing image which was built for testing purposes only that points to my branch of openhabian. You should try using the image that will be posted here once it finishes building it.
