Did you migrate the files manually?

Hi Markus101,

How does one do that? Happy to try, I couldn’t find those instructions. Logically, I would copy a C:\ProgramData\NzbDrone\AppData* over to C:\ProgramData\Sonarr* However no folder by that name exists.

You create it, I presume.

That’s the install folder, so where is Sonarr running from? But creating it will do it too. If you’re using a custom AppData location then point Sonarr to it.
