Issues migrating - machineidentifier

Server Version#: 1.16.6.1592-b9d49bdb7
Player Version#: web interface

I’ve been trying to migrate my Plex database from my mac to the Synology 218+ NAS that the media files are on. I’ve gone through all directions on https://florianjensen.com/2019/01/26/migrating-plex-from-mac-to-synology/ but am getting hung up when I change the Machine Identifier and ProcessedMachineIdentifier in the preference files. When I launch Plex freshly installed (before changing to the original id’s) it connects to the Plex server fine. However - once I change these two numbers, it can no longer be seen by Plex, even though the Server is running. It almost seems that there is a conflict with the other machine, though that version of sever isn’t running. I’ve tried a number of times and am stuck. Any idea why this might be happening? thanks much

thanks, I appreciate the update. i went through all steps on q25 - permissions, moving media folder, leaving alone pref file etc - and still the new server doesn’t see the originals metadata - even though the Synology folder has its contents. Is the fact that Plex user has full permissions over the actual media folder is supposed to make that library show up on the new build? My new build still shows no libraries.

I’m hesitant to offer this as advice.

But I think it’s helpful to mention that Library migration came up a couple days ago with respect to QNAP, and a guy with similar problems solved it. He was technically proficient, but after getting into the gory details about Identifiers with Otto, nothing that looked right was working for him.

The OP solved his problem by moving his Library folder to the new NAS and deleting his Preferences.xml. Letting Plex create that file from scratch gave him everything back.

Maybe that’s worth testing as long as you have really good backups :slight_smile:
I don’t have the link, but a search with Otto, Stefano, QNAP might get it.

To offer some insight / assist ?

Editing Preferences.xml with a Windows editor will have disastrous results.
Windows uses CR/LF for end of line, Linux uses the LF only.
Windows also likes to wrap long lines and break them into multiple lines automatically. This is also fatal to PMS.
