vb5 to vb4 ??
 

I am using vb4 in a live site and don't like to play with vb5 since it is not a fully baked product.

If I use vb5 on a new forum and later if I switch both the license i.e LIVE forum with vb5 and NEW forum with vb4, will it work?

Is vb5 downgradable to vb4?

(I have 2 license - vb4 & vb5 beta)
