What are the means to transfer a forum from kunena joomla to bitrix?

Question

Joomla

There is an old site on joomla 2.5.1, there is a forum on Kunena 2.0.4, you need to transfer it to the Bitrix forum.
Are there any relevant tools that work normally (Whh paid)?
I looked at a bunch of solutions, but they either work crookedly, or don’t work at all, or don’t support working with the forum, but only transfer content such as articles, etc.
Tried https://bitbucket.org/knyazev/joomla.kunena-to-bit... the
Paid module for Bitrix marketplace.1c-bitrix.ru/solutions/yenisite.migrator does not support forum transfer https
://cms2cms. com/ does not support the transfer from Joomla to Bitrix
There were some other scripts, but they did not start or worked very poorly
