This is a MAJOR problem which must be addressed before going any further.
The “Plex” shared folder is available for you to use but not PlexMediaServer,
I need you to create dedicated shared folders for your media and then move your media OUT of the “PlexMediaServer” shared folder.
As example, sifting through the shared folders on my development system, you can see I have dedicated shared folders for animated , movies, tv, and music.
You can use any naming & structure you want as long as it is out of the PlexMediaServer shared folder.
It’s so important you do this that I placed TWO FULL SETS of warnings to NOT place the media anywhere in there.
I don’t see any PlexMediaServer folder. There’s however a Plex1 folder which I moved my content out but the empty folder still has about 3 TB worth of content which I cannot access.
The installer is going to reconfigure your PMS installation (metadata) from the beta configuration to the final configuration.
This action is taken silently during the upgrade. It will sit there “Installing”.
Please don’t interrupt it. It is fully automatic.
It will move your metadata from the beta location to the “PlexMediaServer” shared folder (which is the new metadata location in DSM 7). The “Plex” share is free for you to use or delete as you wish.
When complete, You’ll see the new shared folder. It serves the same function as the old “Plex” share but with different structure and all of the restrictions enforced by DSM 7 .
If you want to read what changed from Beta → Final, please read here.
You may say “Beta” , as in PlexPass/Beta, but from the Synology perspective, there is still a VERY OLD “real BETA” coming from the Synology Package Center which must be avoided. That version is 1.21.0.3744.
