I just tried to upgrade from 2.0 to 2.1. After I rebooted my raspberry all my bindings and items and links were gone.
I then loaded an backup of my system and copied userdata and conf to 2.1 - no luck.
Since I used paperui to create almost everything (at least the homematic/homegear) based items, there were no config-files (which for my mqtt-items worked in 2.1 out ouf the box by the way) and so I had a look at the userdata/jsondb, since I read somewhere that they get saved in there - but all the files are 1KB in size and basicaly empty.
I’m not sure what to do. How can I do the upgrade without redoing the whole system?
