Unable to scan media upon migrating to docker container

[TheDreadPirate]

You cannot relocate data in this manner when migrating. Jellyfin uses absolute paths when referencing metadata, images, trickplays, etc. You have to leave the bare metal Jellyfin data where it is and then modify the docker container's environment variables, which is documented at the link below.

In addition to changing ownership of the files to match the user of the container.

If you wanted to migrate your existing data to a centrally located folder, which is one of the benefits of Docker, you would need to know how to use some SQLite tools to find and replace path strings to the appropriate native docker references.
