Moved Server Now Movies only get metadata but no poster images

When migrating from Windows to any *nix (Unix / Linux) platform, you must also delete the metadata caches. The documentation hasn’t caught up with this step yet. In /var/lib/plexmediaserver/Library/Application Support/Plug-in Support/Data you’ll find a bunch of metadata caches and particularly the HTTPCookies. Delete it all but keep the Data directory. Now restart and refresh the metadata.
