Of course I don’t think there is a way to downgrade to 7.0-41890.
I’ll try the reset approach and let you know how it goes.
I’ve tried to install the last two builds, including the RC, the reinstall keeps failing now. Oh boy…
In case it helps anyone else, had real issues with the migration. thought I followed the instructions to the letter, uninstalled the old version before the DSM upgrade, had all the permissions set but when the upgrade was complete it just added a new library and my old one was inaccessible.
Following some of the posts by ChuckPA I could see that my old “Plex” directory was still full, so no migration had taken place. Followed his instruction to uninstall and remove the data and then try the install again.
This time after about 40 minutes of the blue spinning circle on the install screen I got a warning “the operation failed. please sign in to dsm again” (Note I had set the timeout to 55000 minutes). So i quit and rebooted and tried it again only for the same thing to happen. This time I noticed that files were still being moved from Plex to PlexMediaServer so just left it alone and about 30 minutes later it finished the installation.
Not sure what caused that message but if you get it, just ignore and let the installer continue to do it’s thing.
Thanks @Tigggger. I am now stuck. I am trying to reinstall DSM, but it fails at 53%. I posted on Synology’s forum, hopeful someone can get me back up and running.
Thanks. I actually increased it earlier, but it never comes close to even the default time. It fails after a minute or so.
But again, after resetting the device, it is prompting me to re-install the DSM, but that too is failing. I opened a ticket with Synology… 
That’s the guide I used. now I am sitting at a prompt to re-install DSM, which keeps failing.
Thanks, I appreciate that… It’s a pretty old device, and I don’t want to lose any thing I have stored on it.
I tried the desktop app, but it didn’t find it. I was able to locate it using the find.synology.com though. I was able to locate it with the app prior to me resetting it.
Hi @ChuckPa I was hoping to get help with my situation, I think my post above got missed. Any idea how to go about fixing this?
I uninstalled Plex.
Upgraded to DSM 7.
Rebooted again.
Installed Plex 1.24.2.4973-2b1b51db9 (for DSM 7).When Plex installed/loaded, I never actually got the error message I was supposed to get. Instead I got the message that starts with the blue “Note: If Plex cannot access your media…” with instructions on giving it permissions on shares (it said nothing about migration). Despite this, I still followed the instructions on giving PlexMediaServer Full Control of the Plex folder (including all subfolders). I then gave PlexMediaServer Read/Write permission on my media shared folder. Then I finished the installation. But I never got any message about migration. So I tried also still uninstall reinstall, and it went through the same process I just described without ever mentioning migration. When I try to open Plex, it doesn’t reach my server.
If I go directly to the IP of my NAS with Plex’s port then I get a message from Plex “Not authorized”
It is a “Plex” shared folder. There are still files and no migration log. Now there’s also a new PlexMediaServer folder. I only have 1 volume on my NAS.
Right click on the PlexMediaServer/AppData folder → Properties
See how much is in it.
Wait a minute or two
Repeat that step and see if it’s getting bigger
Plex folder: 8.64 GB
PlexMediaServer/AppData: 2.9 MB, unchanged after several minutes.
Alright. That sounds like an orphaned installation from earlier.
-
Uninstall the DSM 7 application – ERASE option. It will remove that 2.9 MB from the PlexMediaServer shared folder.
-
Reinstall the same SPK file.
-
Now the migration will start. (Migration does not happen if it sees what looks like a valid, even if empty, installation in the target folders )
@ChuckPa
SUCCESS! Thank you. That worked 
I saw the message about migration as well as the blue text about setting permissions for media (which I had already done from before). And because I had already set the Full Control permissions before, I didn’t have the red error message. So I didn’t need to reinstall yet again.
Thank you!
Hi
i just upgraded to dsm 7 smooth transition to plex server public 1.24.1.4931 got the migration log files in the old plex folder. I have a issue when i want to upgrade to 1.24.2.5000 my synology server is no longer accessible. When im back with 1.24.1.4931 my server is accessbile again.
What’s wrong ?
Thank You
Ut oh.
Let me check on that.
I just installed 1.24.2.5000 on the ARMv8 (DS418j) which is my development system.
Everything exists in the package as it should.

The proof it’s the new packaging is the dsm-file-moving script which is new in 1.24.2 and above.
can you verify what you have ?
Hi,
I am running 1.24.2.5000 and I have a crippling 99% volume utilization when Plex is running (even idle). As soon as I stop the package, my DSM 7 goes back to being responsive.
If I turn on Plex again, it’s fine for a while (a few hours) and then it slows down to a crawl again and I have stop the package.
I have a DS3617xs.
Thanks!
Did PMS complete installation or are you speaking of interrupting?
Which version of PMS did you upgrade from?
It is known that, dependent of which version you upgraded from, PMS will catch up a great deail of tasks such as metadata updating, etc. (the new scanner and agents)
I do know it will settle out again once it’s fully updated.
It might be a good idea to grab the logs and attach them so we can actually see what it’s doing.
I’m going to try another PC in a bit. My desktop died, so I am using my work laptop, which for all I know is locked down in some way that is interfering with the wifi.
