Ok, for your installation it wouldn't be feasible, but the OP states 
that he only has approx 100 unix users, with only  about 25 of them 
connected to a samba DC. It may be possible to add the other 75 users to 
the DC and then perform a classicupgrade to S4, but then it may be 
quicker to start anew. I think that the OP needs to tell us just what he 
needs the finished setup to be and if Windows is involved in any way.
