v18 Upgrade option not visible

[Digit_Man]

Hey Guys,
One of our managed sites has the V18 upgrade button missing.
I saw that there was an issue few months ago but that seems to be fixed.

Only update available is New 16.0 Update 7 FINAL 16.0.7.1078
However, when I attempt this update, it just logs me out and doesn't do anything.

Anyone had the same issue?

It seems you're running an older version of v16 explaining why you wouldn't see the upgrade button. Also, do bear in mind that anything older that v16.0.8.16 is no longer able to activate so even if you do manage to upgrade to v16.0.7.1078, your PBX will fail to activate and you'll be forced to take a backup, uninstall and re-install, hence that is what I suggest you do right from the start.

Is this an on-prem instance? Simply take a full backup, move it away from the machine, deploy a machine using our 3CX ISO and then use the backup to restore during installation. You end up with a clean OS and 3CX v18 with your current config restored.

Thanks for the reply.
Before I go down this path just want to confirm something.

Looking at the DOWNLOADS_URL parameter.
The I see a difference between a site that's working and could upgrade vs one that can not.

https://downloads-global.3cx.com/downloads/v160 (Working)
https://downloads-au.3cx.com/downloads/v160 (Not Working)

I didn't think twice as we are in Australia.
Would this have any noticeable difference if I changed it? Or will it still not work?
More to the question, what will brake if I change from an AU version

It won't make a difference and that is not the reason you do not see the upgrade button. It is due to the current version you are running which is old.
