Changing keyword scopes?

I just took over administration of my group’s RT instance (running
2.0.15). Right now we have one queue, and all of the keywords are
global. However, I need to add a few more queues, and they need to
have a completely different set of keywords. Is there an easy to
change the scope of the existing keywords from global to just a
specific queue, without losing the keyword selections for the tickets
in that queue? Do I have a painful database munging session in my
future?

Thanks,

David
