Synology: DSM 7 Installation Archive -- Archived from main thread

At this point, if it didn’t ask you to fix the permissions – is where the deviation from normal occurred. That’s a clue it didn’t detect at least the basics of a DSM 6 installation existing.

It’s not a big deal.

Now that you have the package installed, we can get your DSM 6 pulled over

  1. Uninstall the DSM 7 app with ERASE option (we don’t want that empty one)

  2. Manually set the permissions for the “Plex” shared folder before installing again
    – Use Scenario 2 and it will open the Plex share up so the installer can properly get in there .
    – Make absolutely certain you check the “Apply to this folder, sub-folders and files” checkbox along the way. Without this, you’ll get errors and make a mess.

  1. PMS 1.29.2 is the “Public” DSM7 download. Use it please.
    (“Synology” download choice is DSM 6, “Synology (DSM7)” is DSM 7.
