Migrate openhab 3.2.0 to another host

I have to move my OH 3 installation from one host to another. Both hosts are running docker containers. I already copied userdata, addons and conf, but when I start the new container none of my items, things etc. are present. Did I miss something? Does anyone has an idea what could be wrong or how to debug this?
Thanks in advance

This was a stupid one… Not all of the file were copied correctly :man_facepalming:
