Synology - DSM 7.0 Release - Plex Installation (Not Operational) Issues

Then I started it, and it gave me the standard wizard for a new server. So I clicked Next, thinking that I could see what it was going to do, and it would walk me through the migration.

Your suspicion here was correct.

You were expecting it to complain / ask for permissions to the Plex shared folder but didn’t get that.

RED FLAG

The permissions on the Plex share (not the PlexMediaServer share – which is controlled by DSM) were so locked down (did you play with those permissions at some point?? Hmmmmm) the installer couldn’t find it.

The installer will create a new server when it can’t see a “Plex” shared folder.
(Which is what you have here)

To recover from this:

1. Uninstall the existing DSM 7 package with ERASE option
2. Using this How-To, Grant permission for System Internal User PlexMediaServer to have Full Control of all files and folders in the Plex shared folder.
3. When this completes (it will take more/less time depending on how much media you have indexed in Plex), you can proceed
4. After it completes, Install the DSM 7 SPK file again. It will detect the contents of the Plex shared folder and begin migrating it to DSM 7.
   – DO NOT INTERRUPT IT
   – DO NOT NAVIGATE AWAY from that page
   – When it completes, Double check the popup message at the end for errors.
