Hello!
I'm having an issue since upgrading to TNAS 6 from TNAS 5 where my UPS connected via USB no longer gets detected.
I'm also having a load of other slightly frustrating issues...
Here's what I've done
[TNAS OS 5] - Backed up ALL data and configuration files
[TNAS OS 6] - Initially worked fine, I had to recover from nothing though as a further update seemed to have crashed the system - no biggie, I could have done something wrong and everything was backed up, so I nuked everything and re-installed. This worked, now on the latest TOS version.
[UPS - not working]
This is not listed under supported models (PowerWalker 1500V) however worked just fine on TOS 5. I use the TNAS as a NUT server with Home Assistant elsewhere on my network so that's kinda broken that integration. Not the end of the world but frustrating seeing as this worked before.
[User Accounts - working]
The backup of user accounts on TOS 5 was... Not great. User accounts would not be restored even on the same version as the password was missing. Okay, fine. I backed up the full system config instead and restored on TOS 6 - this worked and passwords were the same, awesome!
[Settings - Partially working]
Well, everything did get restored from the old to new version in relation to settings, except now they appear to be immutable - I cannot change the port of the web GUI. Even if it say it was changed, I'm stuck with the default ports (5443 for HTTPS for example). Again, not the end of the world but TNAS.online no longer works and the default HTTP to HTTPS redirection directs to the expected port 3443 - even though the system responds on 5443. When trying to modify the settings to port HTTPS according to settings back to 5443, it errors out saying it's already in use... Great. So, that's broken.
SNMP - that just doesn't work. Changing the setting here does nothing.
Everything else works fine and I can't just not use the old config file because I need the user accounts. I also have groups and specific permissions on folders / user storage areas so this is out of the question.
Rolling back to TOS 5 might be an option but I don't want to remain on an outdated TOS version when a newer version is available. After all, outdated systems are more prone to vulnerabilities (more so when networked)
[Specs]
NAS: TerraMaster F2-422 with Intel CPU, 100/1000/10000 NIC and 2x12TB RAID1 HDD
UPS: PowerWalker VI 1500 CSW IEC UK 360W, 10121129
Any ideas would be much appreciated if anyone knows of any kind of fix without having to nuke the system again or remove user accounts.
Thanks in advance!

Hello!
I'm new to the forums, not new to TNAS, I recently figured the command line out and so will be exploring ways to troubleshoot / resolve some problems I've experienced in effort to help others in the same situation.
Hopefully I can help!

Re: [Help] TNAS 6.0.794
What is the BIOS version of your F2-422? (It can be found under Control Panel - System)
I need to confirm whether your NAS model is part of the batch compatible with TOS6.
What was the TOS version before you updated to TOS6? Have you ever followed installation instructions to upgrade from 5.1.145 → 6.0.530 → 6.0.770 → 6.0.794?
Regarding the UPS issue, you can collect a system report and send it to the support email for checking.
(TOS Desktop > Technical Support > Report Issues, Please attach the URL of this post)
The Web GUI port can be modified under Control Panel - Network - General.
Due to significant version differences, TOS5 configurations may not be applicable to TOS6.

Hi TMzethar,
Thanks for replying - BIOS Version is MAPL0303V17
The version prior to install I can't recall but I believe it was the latest TOS5 release (whatever that was)
I did read that there was a specific way to upgrade somewhere on the forum and followed this - I may have done this wrong and broken it which landed me in the situation of having to nuke the system and try from scratch as the Web GUI just didn't respond and network shares wasn't working. That is now resolved though.
Regarding the UPS issue, I'll get this into support shortly

Re: [Help] TNAS 6.0.794 [SOLVED]
Just a quick update - all of these issues were as a result of uploading configuration files from TOS5.
It's a real shame that users can't be carried across but since resetting the config, UPS now works and all settings are functioning as expected.
Note to self - stick to the instructions.
