@cornholio: I was more interested in the structures behind it, which I don't know as an outsider.
The Kunena Forum can take over the complete user structure of Joomla with all rights etc., which is quite complex, at least that's how I understood it on the Kunena Forum website.
Of course, you can also create and operate the forum separately from the website (with additional rights management etc.).
The current OS
That's a silly question, sure. Is the server environment created by yourself?
Or is the server environment managed?
Notes:
1) If we have installed our own server that runs on Ubuntu, the server may need to be updated.
1.1) Ask the person who installed the server!
1.2) Do nothing without a backup!!!
-- when the server is cleared and done --
2) Check which PHP version is installed
2.1) Update if necessary
3) Check which database is installed (probably MySQL, which version)
3.1) Update if necessary
4) Check which domains are available and where they are forwarded to.
4.1) List of all domains with internal/external destination folder
4.2) Check all start folders of the domains ‘.htaccess’ whether redirects exist here www without www https forced etc. ...
5) Check the user administration of the forum to see if it is connected to Joomla.
5.1) If no, much easier, if yes, think again!
6) Create new folder for new forum
7) Install new forum incl. new database etc.
Possibly check with the forum manufacturer Kunena whether user data, posts and images from the old forum can be exported/imported to the new forum.
etc.
But the beginning is very important, because this is the basis for everything else and when I look at what @JT has provided us with as a layman, I get the impression that it is not a finished server (which a service provider takes care of), but that the server was set up itself, which then also has to be maintained!
There are 3 active forums at the same time,

I hope not!
My site is accessible with and without www, but there is only one page.
All visitors who come to my site without WWW are redirected to the WWW page on the server side!
Google and Co. don't want duplicates either and usually remove such things from the INDEX! which would be a great pity!
I have the impression that I have not yet fully understood how the whole thing is structured and that we are talking past each other in the wrong places.
Ich schätze mal, das liegt oft auch am Problem der Begrifflichkeiten und auch sicher an meinem Englisch, was von DeepL kommt
