please see the following faq, opssrah:
phpbb in xoopsif you don't have lot of forum messages in your current phpbb, i would suggest you to start fresh using the cbb.
the current x-phpbb port we have does a core hack, which will limit you in upgrading your XOOPS or phpbb. the latest news i heard from koudanshi (the author of bbpixel/x-phpbb) that he will have more time in working on the phpbb-xoops integration.
