How to successfully migrate Plex from a Mac to a QNAP NAS?

Server Version: 1.21.1
Player Version: NA

I’ve tried a few times now to migrate my Plex Media Server from an old (2009!) iMac to a new QNAP NAS (TVS-872XT) but it’s failed each time to transfer my library data. I’m new to NAS’s. Any help is appreciated.

My media files and source ‘Plex Media Server’ are backed up a few times over on other drives.

I recently successfully migrated the very same library data from one Mac to another Mac and it’s loaded the libraries successfully… but I’d prefer to use the QNAP to host the PMS and do all the transcoding.

Here are the steps I’ve gone through:

  • Disable Emptying of Trash on Source System (Mac)

  • Sign Out and Stop the Plex Media Server on Source System (Mac)

  • Install Plex Media Server on the Destination System (PMS V1.21.1 on NAS)
    Setup wizard doesn’t launch on start, ‘no soup for you’, message.

  • Sign Out and Stop the Plex Media Server on the Destination System (NAS)

  • Copy Server Data From the Source System

My PMS folder is quite large (~220Gb) and I’ve tried two ways:

Zipping > Transferring > Unzipping of ‘~/Library/Application Support/Plex Media Server/’

Using ‘Carbon Copy Cloner’ to mirror ‘~/Library/Application Support/Plex Media Server/’ directly to the destination folders (listed below)

  • Copy Additional Server Settings From the Source System
    com.plexapp.plexmediaserver.plist
    (As far as I’ve seen this file is only for Mac PMS installs)

  • Place on the Destination System

I confirmed using SHH that Plex on the QNAP is installed at:
/share/CACHEDEV1_DATA/.qpkg/PlexMediaServer
That the Library is located at:
/share/CACHEDEV1_DATA/.qpkg/PlexMediaServer/Library/Plex Media Server

In order to make that location accessible via UI…
My first try was to use PMSLibShare to create a folder into which I could copy ‘/Plex Media Server/’.
My second try (after a full uninstall and reformat of the NAS) was to create a symlink in the Public folder using the following found command:
ln -s /share/CACHEDEV1_DATA/.qpkg/PlexMediaServer/Library/Plex\ Media\ Server/ /share/Public

Both strategies revealed a PMS folder accessible via File Station. I fully copied over the data (which was VERY slow (1–10Mbs through a USB3 drive plugged into the QNAP) it took about 11hours for ~220Gb, even though other NAS transfers are a good speed).

** This is also where I assume I’m messing up as I’m not certain I’ve copied the data to the correct place. After this point each time I’ve proceeded to:

  • Reboot the Destination System (NAS)
  • Start the Plex Media Server
  • Launch Plex Web App

I see the ‘no soup for you’ message. My library titles have appeared on the sidebar but are greyed out and can’t be clicked on or edited.

  • Sign Out and Back in to the Server

No change. I still can’t click on any media libraries or edit library locations.


That’s it. If I’m missing something (or if anyone know why just the PMS transfer takes so long) please let me know. Thanks!
