Well , I don't think this is a hard work.

select POST_ID from ubbt_IMPORT_MAP where OLD_TOPIC_ID = old_topic_id;
select TOPIC_ID from ubbt_POSTS where POST_ID = postid;
insert into ubbt_WATCH_LISTS values(userid , topicid , 0 , 't')


I think it is easy to implement in the importer.
Hope ... there will be a importer-patch... smile
