[Samba] upgrading and moving to different servers

[Adamiec, Larry]

I am currently running Version 2.2.8 on a Solaris 9 SPARC machine.  I
need to move my Samba server to a Solaris 10 SPARC machine.  I would
like to install Version 3.0.23a on the Solaris 10 machine from source.
I need to install from source because I need to change the prefix from
/usr/local/samba to /opt/servers/samba.

Do I need to worry about other configuration options?
Can I use my old smb.conf file?
Should I just FTP my old version to the new machine and upgrade to
Version 3.0.23a?

Anything else I need to worry about?

Thanks in advance.

Larry
