   Huh ? Sure you can upgrade from a major version to the next - we do it
all the time with CentOS .  The simplest and quickest way to do it is
with a boot.iso CD and a http mirror. Just make sure you don't have any
old .rpmnew files from previous updates as they tend confuse you after the
update. This will get you from say 4.5 to 5.1 . A yum update will get you
any additional patches. Last step would be to ( optionally ) write a small
script to find obsoleted packages ( in 4.5 but not in 5.1 ) and possibly 
delete them.
