Trying to identify correct version number on a v12 install

[Mike Jones]

Sorry, I know this seems simple but I do not have any experience with older version of 3CX (Windows).
I have been working mainly in the last year with v15 and v15.5.
I just inherited an older installation with a new customer and am about to take them up to the latest version.
I have read about the correct process on updating what version to what (v12 to v12.5 to v14 to v15.5).

Here is my question.
At the top it says "Management Console v12.0.32816.397".
When I look under Settings > 3CX Phone System Updates > 3CX Service Packs/Updates, it shows up to service pack 2 has been installed (shows "up to date").
Starting with service pack 3 and above, it shows "out of date".

I am not sure exactly whether I have a v12 or a v12.5 here.

Any help would be greatly appreciated.

As it says v12.0.32816.397 this is version 12.0 SP2 - dated Oct 2013.

Version 12.5 would be 12.5.xxxxx

Hello @Mike Jones

You will need to be at SP6 of v12 to be able to upgrade to V12.5 as mentioned in the upgrade path found here: https://www.3cx.com/docs/manual/configuring-your-pbx/#h.k52p90c8u3ym
