If you can wait a few days, you’ll have regular access to the Plex data.
It will be accessible again as the “PlexMediaServer” shared folder.
(I managed some dark magic)
I can give you the working preview now if you’d like.

Preview would be great!!! I can wait. I wanted to install the preview but I just couldn’t talk myself into installing it.
I put the 1.24.2.4955 (alpha) build of PMS up for us to use.
It’s pre-official QA testing. PMS seems OK but still might have issues functionally
Packaging wise — SOLID! 
I am interested but I’d rather wait for proper release if that’s ok.
This is my migration log if you need it. (no errors

LAST question since we have probably sorted everything out.
What should i choose when I install the upgrade? Does it matter? It’s just logs 
If I install the preview should i choose “pms internal location”? I suppose that’s the new hidden pms folder?
PS: THANK YOU SO MUCH FOR ALL YOUR TIME!
My installation seems to have worked. Plex still works fine. The Plex is empty and only have the Migration.log file. But now I just can’t really see where the files should be.
But my only main problem seems to be for when I’m adding new files to my TV Shows Library, Plex doens’t automatically anymore when they are added.
It is updating my movie library automatically when I add a movie to my movie folder.
So it is TV Shows with season and all that doesn’t automatically update. I have to manually choose Scan Library.
Does anybody maybe have an idea to solution?
I just followed the instructions to update Plex for DSM7. There are two problems I still have.

Please advise on how to solve these issues. I have the same problems on my Nvidia shield (tube) which makes me suspect that is is on the server side, but I’m not very knowledgeable on this topic.
Thanks in advance.
After migration is complete, the “Plex” shared folder will be empty. I explained it all here in the documentation.
When you installed DSM 7, DSM 7 overwrote the custom Notify buffer size setting you had.
You need set it again.
Which instructions please?
If you used the migration instructions from the forum (my instructions), Please confirm the Plex shared folder is empty
There are multiple answers here ![]()
Logs directory under Plex Media ServerOMG THANKS!! That did it. Adding permission to my Media folder.
Is this where I start waving around a big thick
?

I guess this was asked before but after the migration is completed successfully, can we safely remove the Plex shared folder (that now only contains the Migration.log) as well as the old ‘plex’ user?
Yes and yes. 
I might have an interesting situation on an older DS214.
After migrating to DSM7 I removed all previous Plex version folders & users (or tried to), then tried a clean install.
Unfortunately I didn’t manage to avoid issues. With both versions I tried Plex tries to start, but stops soon after.
Here’s a log from the latest attempt:

The database files don’t seem to be corrupted, but just empty:
Is there maybe a DB initialization script that didn’t run? (and that I could run manually).
Update #1: I just noticed the otherwise obvious “Couldn’t copy file” error - I guess it’s a leftover from a previous install. I’ll clean that up & retry.
Update #2: Ran an ls after uninstalling & rebooting - doesn’t seem to be old leftover files:

I got the same problem for another DB:

This doesn’t seem to be a permissions issue - maybe some different libraries / kernel… What do you think @ChuckPa?

The “alpha” package appears to have bitten you. Sorry about that.
There are several “Packaging 2.0” builds. Have you tried them all?
Also, where is your DB which you have been running on?
So I’ve had a few things happen with the migration. My first try I missed the Uninstall step and ended up with a new server with the same name. I used the migration script posted and did a un-install, re-install with claim token to fix that.
It was working for a day or so, but then stopped responding. I stopped it in Package manager, but then it wouldn’t start back up the log showed database corruption errors. I tried the database repair process with no luck and ended up restoring a database from before the update. It started up then and re-converted the database I believe.
It was working again for a day or so, but today I’m getting database corruption errors again in the log:
Aug 27, 2021 12:01:15.502 [0x7f0fd2b30b38] ERROR - SQLITE3:0x80000001, 11, database corruption at line 69874 of [1b256d97b5]

Hello @ChuckPa,
I have been trying to solve this problem for a week now. I did the manual install, I removed everything from plex of my NAS (even with SSH to manually take off everything that was left).
I can install my server manually. I can even claim it with the token. My plex.tv account will see that the server has logged in as I can see it in Authorized Devices.
However, plex.tv doesn’t see any servers. And if I log in with the same account I used to claim the server, when I log in on port 32400 on my server directly, it tells : Not Authorized, you do not have access to this server.
What am I supposed to do with this?
Can you provide me with the log files?
I looked at your account on Plex.tv
I see “storinator” which was recently deleted. I don’t see any active server registered to your account.
This means one of two things:
Your logs, collected about 2 minutes after startup, will tell me what is happening (it logs in during that startup)
Also. which DSM 7 package version are you using?
I cannot find the plex log file. The location specified here does not exist : Where is the Plex Media Server data directory located? | Plex Support
I see no shared folder for Plex (I had to delete the old one called Plex on DSM6 because it was impossible to read/write in any way after the upgrade. I’m trying to fresh install)
As for Storinator, that is the one I’m trying to get to join again with a fresh install because I wasn’t able to repair the old instance
But I can guarantee that it’s the correct account (confirmed upon install with the token. You get a message with the account that has successfully been joined)
And I can see him in authorized access. As for connection to plex.tv, that is also tested and it’s fully capable to connect to it through the network…
