Here we go – Ride the wild software time.
On Windows
- Turn off all automatic updating
- Disable “Empty Trash”
- Save those settings
- Stop Plex
(we’re about to clone it) - Create a ZIP file of the “Plex Media Server” folder (the one that contains all the metadata underneath it)
On DSM
- Create a shared folder named
Plex
(case sensitive) - In that shared folder, create this structure (old DSM 6 'cuz it’s easiest)
Plex/
Library/
Application Support/
-
Copy the ZIP file to the Plex shared folder
-
Unzip the ZIP
-
After unzipping move the contents if needed to product the following structure
Plex/
Library/
Application Support/
Plex Media Server <-- this will have come from Windows machine
-
Download PlexMediaServer from https://plex.tv/downloads for your Syno
-
Manual install that SPK file
-
As it installs, it will find the “Plex” shared folder and immediately (while installing) start migrating it to the DSM 7 structure.
-
Depending on how much data you have, you might be here a few minutes → hours → whenever.
-
Open a new window to the Synology, Open the Plex share. Look at the file “Migration.log” . You’ll be able to follow the progress
In case you need to see the steps about granting permissions.
