If you mean clone system for your backup in case something happened during upgrade, I recommended to take backup from /etc which contain files system, if something happened for the file system you can copy back or you can use Image application like Acronis and make your full image if something happened just restore it There UNIX /Solaris command called dd it can do image for you too

fresh install is always better, but as Abdulqader said, you can create an image of the whole disk or partition with a tool like dd.
here's an example on how to use dd for cloning a partition: dd if=/dev/sda1 of=/mnt/sda2/sda1.img conv=sync,noerror bs=64K Note that the img should be placed on a different partition which is already mounted on your system, otherwise you will stuck in a loop!

:P Seriously, I don't recommend cloning.
Just a fresh install if you have a new box.

CloneZilla is good to clone a Linux system. Or use rSync to backup your data and then install afresh.
