It would be a great benefit to find a smooth way of transitioning from
Joomlaboard to
Kunena! I can think of one or two
big websites that would gain from this ...
I'm sorry you haven't received an answer. As you know, the developers are working around the clock (literally) on the next version of
Kunena. In the meantime I can only suggest you work through the other ideas that have been offered in the past, for example
Migration from JoomlaBoard to Kunena. I agree, it's not easy and you may have to do a lot of fine-tuning, but if you take things carefully, using a temporary staging area, you should be able to get good results.
Worst-case scenario, leave your old Joomlaboard site as a stand-alone archive, lock it up (prevent new registrations and postings) and build a new website that refers back to the archived discussions. OK?
