Sorry, the HABPanel storage backend had to be changed, and is not compatible.
You can go the panel settings on the OH2 instance, click on “Edit the local panel configuration (experts only)” under “Local storage”. Then copy the code or export it with the button. Go to the same screen on your OH3 instance, and paste or import.
Then on the previous screen, save it under a new name with “Save the current configuration to a new panel configuration”.
Repeat for each configuration you want to migrate.
