[Samba] Upgrading from 3.0.37 to 3.5.9

[Gaiseric Vandal]

I believe you could also use "smbpasswd -w" to dump out the passwd file 
in plain text.  Then you could manually restore the passwords if 
password database got trashed during the upgrade.

The samba 3.5.x packages may actually be "patches" -  which means they 
may check for the 3.0.x packages.  I don't know for sure tho.

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:
