Hi, I was trying to migrate to openhabian from my windows server. This was sucsessful (openhab 2.5.11) on the openhabian. Then i take backup.
I was under the impression I could upgrade from 2.5.11 easily to OH3, but it seems that none of the THINGS is transferred when upgrading. Items and rules transferres fine.
did you use .thing and .item files? If so you should be able to drop them into a fresh OH3 install.
If you’re using openhabian I would adivce to start from scratch with a fresh install. During the pre-release times of OH3 a samba.conf was not pointed correctly (info here)
When using the latstes openhabian 1.6.2 things are working great.
Make sure to read on the backup options openhabian provides.
