My PMS on my QNAP is currently running version 1.9.6.4429 for the 32 bit QTS 2.5. It says that there’s a newer version available but cannot find it.
It shows a 64 bit version for QTS 4.3 but the last time I updated to the 64 bit QTS my Plex server wasn’t found!
Per QNAP request,
All 32 bit Intel NAS units were discontinued in conjunction with QTS 4.2 support ending.
Which model do you have?
I have a QNAP TVS-471… I downgraded to QTS v2.5 because the 64 bit wreaked havoc on my Plex system. I don’t have an issue with updating o the latest version of QTS but the last time none of my devices (Fire TV Stick, etc…) could see my Plex server!
QTS 2.5 ? Please confirm?
yes, it is. I don’t have an issue with updating to the latest version of QTS but the last time none of my devices (Fire TV Stick, TV, etc…) could see my Plex server!
The lowest version supported is QTS 4.3 due to the GLIBC requirement in PMS 1.15.0 and above. GLIBC was updated a bit from the ancient & archaic to 2.14.1. As reference, most distros are now running 2.28 and higher.
Since PMS 1.9.x and QTS 2.5, a lot has changed.
Given its age, it may not migrate well so there is the potential that updating will yield a worse experience than starting over.
If you’re comfortable with the command line, we can migrate most (likely all) of your media watch status. If you’ve watched all of it, you can manually mark it watched now.
One major change in PMS is the requirement for RFC-1918 addressing on the local LAN. This means either a 192.168.x.x or 10.x.x.x or 172.16.x.x -> 172.31.x.x subnet addressing scheme internally.
Is your LAN already setup this way?
Another consideration with QTS which will cause you issue is the changeover to /share/CACHEDEVx_DATA addressing of the volumes.
How do you reference them now? MDx_DATA ?
Right now both of my QNAP devices use the 192.168.x.x addresses. When I set up the PMS I just chose my /share/CACHEDEV1_DATA/Movies and /share/CACHEDEV1_DATA/TV libraries.
Excellent! There have been a lot of cases where folks would have the very old MDx_DATA (MD0_DATA, MD1_DATA…) addressing and they were forced to rebuild because all the volume names changed.
upgrading isn’t going to be too problematic here.
There is a finite set of steps to perform to prevent loss of your existing metadata.
As long as we follow those steps, you’ll be in good shape.
What’s your pleasure?
Go to QTS 4.4 and current PMS?
NOTE: When you upgrade to current QTS, if you have a Virtual Switch, the migration isn’t smooth. It’s usually best to delete and recreate it after the fact.
Yes QTS 4.4 and current PMS. Will my TV an other devices be able to access the PMS? I hate to go thru the pain again if its not gong to work. 
When installing the new version, the most important points are:
Given the number of versions skipped, there will be a lot of database migration work required.
This will take a few minutes (maybe 3-5 minutes) to complete.
Let PMS come back to its fully idle state – as shown in the QTS CPU monitor (upper right).
Now open the server using LAN IP:32400/web and, if you’ve been signing in, it will be good to go.
IF you’ve been running without authentication (no sign-in),
Go to http://app.plex.tv and sign out first.
This keeps the browser and server in sync with each other during that first connection post upgrade
