In a test VM, just re-provision Samba, then learning from where that
puts the files, move the files to the new correct locations.  Finish
with a samba_upgradedns --dns-backend=BIND9_DLZ to fix the hard links.

Or do the reverse, by setting the various paths in the 'new' smb.conf
to point at your old installation directories. 

The most critical paths are 'private dir' and what [netlogon] and
[sysvol] point at, but of course there are other persistent tdbs like
printing that may matter on a site-to-site basis.

I hope this helps.
