The existing Samba directory structure is not standard.  I believe the engineer who built the Solaris install transferred all Samba 2.0 directories from the old server to the current server and then created additional directories for the install and symbolically  linked some of the old files to the new install.  Anyway, Samba is installed in two different structures on the server:  Samba and /etc/samba...  and /etc/sfw....  We are using the "sfw" directories:

After having met too many issues to do a "simple" migration from 3.0.X 
to 3.5.6 (something like copy & paste .tdb files, pdbedit 
import/export...), I made a script that create accounts based on old 
uid, SID (both computer and user accounts) and passwords. Keeping the 
old domain SID, these parameters were enough to provide seamless 
migration for users.
