Question Migrating from phpbb3

Not sure if this is the correct place to ask my question but hopefully you will be able to help me.

I am trying to migrate from phpbb3 to Kunena and I found this page for instructions. It goes well untill step 7. There I get the following message:

Importing data from phpBB

Connecting to Database... OK
Populating Categories... OK
Invalid query:
update tdu_15-25_2.he953_fb_categories, tdu_15-25_2.he953_fb_messages set time_last_msg=tdu_15-25_2.he953_fb_messages.time WHERE tdu_15-25_2.he953_fb_categories.id_last_msg=tdu_15-25_2.he953_fb_messages.id and id_last_msg>0
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-25_2.he953_fb_categories, tdu_15-25_2.he953_fb_messages set time_last_msg=tdu_1' at line 1

When I take a look at the Fireboard link, it has no actual topics although it does show the number of topics and replies on the mainpage.

So it looks like the migration is done half.

Does anybody know what I can do?

Many thanks for your help.

It looks like I found the solution. After a lot of googling I found the Kunena Migrator. This component can be downloaded here:

joomlacode.org/gf/download/frsrelease/16076/69871/com_kunenaimporter_v1.7.1_b271_2011-11-16.zip

I only had an error when pressed Import. Unchecking 'Import Users' solved that problem. Not sure yet what consequences that will have. But sofar everything looks good.
