Sure,
moderators will have that in their ability-list. One of the ideas is to bring those threads from the old forum that are relevant to the new one. I guess that it makes no sense to import all of the "how do I plug my board to the computer" topics, with just one or two of the most significant ones would be enough.
Also, it is possible to make subcategories in the language boards, and this is a chance for the international moderators to arrange the posts in a better fashion. E.g. Spanish is always a challenging language because there are so many different countries that are speaking it, and some of the issues we usually work with are strongly localized like where to buy components and so on.
