Upgrade from RHEL3 to 4 for free!
i got this email from RHN
Red Hat has created ISO images for all releases of Red Hat Enterprise
Linux and made them available on the Red Hat Network (RHN). You can
download these images and use them as your new installation media if the
CDs that were shipped to you do not install or if you require an
installation with a more recent kernel and security updates.
someone have try this OS upgrade? any problem?
