I don't use #! myself so I can't check, however you can find out how far away you are for yourself. Check your sources list (either /etc/apt/sources.list or a set of files in /etc/apt/sources.list.d). Are you pulling in packages from Debian repositories already? If I remember correctly #! had its own repo which contained its WM configuration and whatnot but the rest was stock Debian. If so, there's probably no action required. If not, I would wait and see what some more experienced #! users are doing with repository migration. The Crunchbang forums are probably a good starting point.
