Please correct me if I am wrong but Release openHABian v1.7.1 · openhab/openhabian · GitHub states that it is recommended to reinstall (Please note that if you choose to upgrade and not reinstall, you are on your own, don’t expect to get support from the developers of openHABian if something goes wrong.).
Furthermore (openHABian | openHAB) at Availability and Backup: 4. Use the openHAB integrated openhab-cli tool (opens new window)to interactively backup/restore your openHAB config [menu option 50/51].
Adittionally under Setup notes: You can have openHABian import a working openHAB configuration right from the start at installation time like when you migrate or reinstall
Given these options it seems logical to me that this would be the way to upgrade openhab and restore my settings.
Thus I’ve tried the upgrade by using a freshly flashed SD card with openhabian 1.7.1 and restoring via the openhabian.conf (naming a initial.zip file to restore a backup) option and a second time by restoring my backup after a new fresh install. Both resulted in overwriting of the org.apache.karaf.features.xml file.
So I am clearly missing the recommended upgrade path (including restoring an old configuration). But how should one go by upgrading and restoring a working configuration? I am not able to find it in the docs.
