Call me dumb but I would expect a normal upgrade to move the files and remove files that are no longer needed. It’s ok if that is not the case - just not something that I would expect.
I my OH installed through openhabian so I did the upgrade using openhabian-config tool as described in the upgrade instructions.
So, more important question is - how to fix this? I did try re-running the “apply improvements” thing and selecting the option for installing samba shares - that doesn’t seem to do anything.
