Using PlexMediaServer/AppData is where the mistake was made.
DSM 7 changed so much that we had to process all the metadata as it moved from DSM 6 to DSM 7.
This also applies to anything imported from another OS.
If you follow this procedure,
-
You put your metadata in the Plex shared folder structure.
-
The installer will import the data by performing all the processing.
-
When complete,
– Plex shared folder will be empty
– PlexMediaServer will contain the metadata -
Points to remember
– The "PlexMediaServer shared folder cannot contain an AppData directory.
The installer will not knowingly overwrite an installed PMS server as it runs.
– When you start this process, Package Center will sit at “Installing” until all work is complete. DSM might give warnings about Operation Failed… Ignore them
– If you navigate away from the page, you won’t know when it’s done UNLESS you look at the ‘Migration.log’ file in “Plex” shared folder (appears after about 2 minutes when installing)
