If you're saying what I think you're saying, I think Hapuga made a thread about that somewhere but I don't remember where.
EDIT:
Okay so if you're asking for how to convert 1.7 maps to 1.3, the thread is here. And seriously, you should pay a bit more attention. This thread is stickied for a reason. But not only is it stickied but it is in the same forum as this thread, I'm actually a little surprised you missed it when posting this thread.
