want to move buddypress from main site to sub-domain in multisite

hey my friends :slight_smile:

So. I've got buddypress up and running so far on my main site (http://www.intothemythica.com) and am realizing that I actually want the buddypress part (called 'Akasha') to be on it's own site, allowing me to have a more specific buddypress menu and other stuff just for community while the landing site (intothemythica.com) presents the larger overview of the project

i've got a few users already. would like to move buddypress over. how can this be done cleanly?
