Upgrade to FC4 from FC3 without having to re download and then burn cds and recreate partition?

[Sam Johnson]

Hello,
I am very excited about the soon release of Fedora Core 4.  However, I
want to upgrade from Fedora Core 3 in an easier way than doing the
procedure that is required for the first install you do, downloading
all of the ISOs, then burning them to discs, and then use Disk Druid
to erase partition (and all of my lovely data) and recreate it.
I hear of alot of people saying that they upgraded, and am curious
about how it is done.

Thank you,
