I completely understand, it looks like I am going to have to merge all the sites into the lawfirmname.com site and just work very hard on building the practice area pages up to rank well.  The transition is what I am concerned about, but I guess I will just try to make it as painless for their rankings as possible, by taking down the microsites slowly as we build up the lawfirmname.com site and definitely not linking any of them together in the meantime, just leave them like they are until I can take them down.  Thanks for your responses.
