Thanks again, I will give it a try on my local test system next weekend and report what happen to me
ubb use the following tables on my system who need to be converted:
ubbt_POSTS
ubbt_TOPICS
ubbt_PRIVATE_MESSAGE_POSTS
ubbt_PRIVATE_MESSAGE_TOPICS
ubbt_PROFILE_COMMENTS
maybe there some other with such entrys but this can be done by hand (example ubbt_USER_PROFILE for signature text)
