If you want to do the classicupgrade on a new host, then simply shutdown
Samba on the old server and copy the databases listed in the Howto and
your smb.conf + /etc/group to the new server. Migrating from tdbsam is
quite simple. Nothing more should be needed.

Then install Samba and do the classicupgrade on the new host. It's all
described here, what you need:

If you have any specific questions or problems, just ask.
