Question Convert Migrate Kunena to phpBB3

I know there is methods to go from phpbb to Kunena, but is there an existing method or planned tool to accomplish going from Kunena to phpbb3 ?

Here is why....I plan to start with Kunena, but over time if the forum gets too big to handle 1000s of members and 100,000+ posts and large traffic (in addition to the main site as well which has a membeship system, user manager (juser), and other components running), I will more likely need to move to a higher-end forum system that can be separate from the Joomla site queries.

So if there is no method or planned method, I will know the direction to go at start.

Thanks in advanced.

There is something in the phpBB forum, but it's a converter to phpBB2. So you'd have to upgrade to phpBB3 after the conversion:

Actually is a fireboard converter, but it seems that kunena uses the same tables that fireboard. But it's not a good idea, I advise you.

Why don't you use Joomla! with a phpBB bridge? I think it will be easier for you...
