Like, moving from one Linux distro to another etc.?
That also should be easy - most places to look for are (may depend on
how Samba was compiled, though - see "smbd -b"):
user profiles, logon scripts, printer drivers etc. - defined in smb.conf
The most important files would be (assuming users are stored in LDAP)
All other .tdb or .dat files are not really needed (yes, they may
contain printer settings, something cached, but probably, can be skipped
in most situations - shouldn't make much harm to copy them, though).
