[expert] Upgrading from 7.2 to 8.0 over network?

[Brian Hartman]

Hi, all.

I would like to upgrade from 7.2 to 8.0.  Unfortunately, I don't have a 
CD-ROM burner, so I can't just download the ISO and install.  Is there a way 
to do an installation over a network (from an FTP site, for example?

TIA.
