You should always do a fresh install with the latest version in any case.

However, you may want to move an existing set up to a newer Pi, and this
can be done even if that older install wouldn't work on the new Pi. What
you need to do while running on the old Pi is to do a:-

sudo rpi-update

This will install all the newer components in /boot to allow use of any
Pi. There is one gotcha though, you need to ensure your boot partition
is big enough for al the new files. Older installs may have only had a
64MB boot partition, but 256MB is recommended now.

You can use gparted to enlarge the boot partition, but that requires
moving the root partition upwards, which may take a long time for a
large card. It may then be quicker to reformat and reinstall.
