It's better if you reinstall using the ISO you Downloaded,
actually easier
only if you not chaged configurations outside your userhome
As rex said, Otherwhise you'll need to Download the DVD and then
attempt
the upgrade selecting KDE as desktop enviroment
there is NOTHING to select
upgrade does not change the desktop or usersettings
but I'll always recommend reinstalling
i do not because i have made some hundret upgrades and
we are not on windows where you permanently reinstall
your OS
never needed to reinstall linux and with
dd if=/dev/sda | ssh root@liveos "dd of=/dev/sda bs=16M"
you normally do not need this by switching the hardware
