G'day, retro, and welcome to
Kunena.
I really do need to create a new topic called "Moving/copying/updating/migrating from K-something on Joomla-something to K-something-else on Joomla-something-else"

I don't know how out of date it is, but my suggestion is to start the process by getting J! 1.5 "up to speed" before moving forward. The next logical step is to get your old J! 1.5 extensions up-to-date (as best you can), too. After doing that,
that's when I would start the migration to J! 2.5 or J! 3.1.
K 1.5.8 is
how old? I think it was released in January 2010!

Why would you do that? K 1.6.5 was released in July 2011 and, like K 1.5.8, it is so old I don't think anyone remembers anything about that version, either. The fact of the matter is that if you want to use
Kunena on J! 2.5 you
need
K 1.7.2 as a
minimum.
It's really difficult trying to prescribe, within a forum context (like we're using here now) how to resolve each individual case of upgrading from K-something on Joomla-something to K-something-else (possibly on Joomla-something-else also). And, yes, the process is tortuous and it can be "nasty" and you can spend days or even a week if you work through the issues one by one. It largely depends on how much time (or money) you are prepared to invest in the exercise.
This topic
may help:
www.kunena.org/forum/154-Miscellaneous-o...site-to-a-j-3-0-site
At the very least there are many good general pointers in that topic that will help even if we are dealing with upgrading from K 1.5.8 on J! 1.5.
