[Forum] Forum update and category/subforums problem

[doli]

Hi,
I updated my forum to vb4 and did some small forum reorganization.
In 3.8 I had big category Discussions with some forums and subforums ie.
Discussions:
- Poker Strategy, subforums: Holdem, Omaha

Now I changed Poker Strategy to act as top level category so in vb4 I have:
Poker Strategy
- Holdem
- Omaha

Unfortunately I forgot that users in 3.8 were writing general strategy posts directly in Poker Strategy forum, now when this forum has become top level category they dont have direct access to these post.

I'd like to add new forum: General Strategy and put these Poker Strategy posts there. Any idea how to do it?
