I would note that our importers don't actually support vBulletin 3.0 -- I believe version we have support for is 3.6 -- so there would need to be an upgrade. It's theoretically possible it may work, but it's not designed to handle that version (so if you had problems, we'd have to recommend using a source version we cover).
Thanks Brogan, my character is Big-5, I saw XF has Big-5 language pack, do I need conversion database to UTF-8, than do import and add Big-5 language pack?
