Of the rPi? you don’t really need them since you will reconfigure the new host
I general, check the files within the $OPENHAB_CONF folder (/etc/openhab2/*) for data corruption
$OPENHAB_USERDATA folder (/var/lib/openhab2/*) is also important (mostly the jsondb)
But there is no such folder /var/lib/openhab2/jsondb/
and no /var/lib/openhab2/config/
I don’t know the exact OH version, but some “stable” OH2 beta, no snapshot. Maybe the folder structure is different at this older version - or these folders coudn’t recovered by Linux reader
All your config files in $OPENHAB_CONF (Linux apt: /etc/openhab2/)
Most of the files & folders in $OPENHAB_USERDATA (Linux apt: /var/lib/openhab2/)
All subfolders without tmp & cache
Optionally (if you are using manually deployed addons): $OPENHAB_RUNTIME/addons (Linux apt: /usr/share/openhab2/addons/) (only the contents of your addons folder…e.g. a *.jar file)
So:
(1) Backup the above from the older OH2Beta3,
(2) Deploy a clean openHAB 2.1 Stable Release in your system,
(3) Restore the contents of these 2 folders (CONF & USERDATA)
