You do not install
phpMyAdmin in Joomla.
phpMyAdmin is a free-standing piece of software, developed in PHP, that is installed on a web server and allows you to connect to, and manipulate MySQL databases. Any quik search of the internet would have explained that to you.
phpMyAdmin has nothing to do with Joomla.
I notice this topic started two weeks ago and, from the looks of things, you have not even got to the first stage before you're in a position to start to work on exporting the database tables from your original site.
Manipulating database tables is not for novices and it is not for the faint-hearted. It can take years of practice to develop the skills necessary. If you don't know even know the most basic things about the tools that you need to work with databases, it makes the task virtually impossible.
When people ask "how can I move my
Kunena forum from one place to another", we can give them the technical advice about what tables are involved and we can give broad directions about what they may need to do but, in a community-driven, web-based, self-help forum such as this, we can't be expected to provide detailed step-by-step instructions that cover every possible contingency. To write detailed step-by-step instructions that explain how to do this, for all skill levels from novice to seasoned professional, this would require a documentation manual the size of a thick book.

4. Now you must configure your installation. There are two methods that can be
used. Traditionally, users have hand-edited a copy of config.inc.php......
This isn't
our documentation and I have no idea what is meant in the context.
Let's get back to the original question

Unfortunately we are having a bit of a problem finding an export/import function in Kunena. Does it exist? or how do we do?
There is no export/import function in
Kunena. That's the simple answer.
If you know your way around SQL databases and Joomla then, for a skilled professional, you can achieve the task. If you don't know your way around SQL databases and Joomla, then you can waste a lot of time trying to pick up the skills on-the-fly. If I was in your position and I thought that it was
worth the effort to preserve an old forum's topics (but I lacked the know-how to do the job myself) I would pay someone else to do the job for me. In the hands of a skilled professional, the task of doing what you've asked would take a few hours. Compare a few hours to the two weeks you've spent and the results that you've realised.
