First boot from the live image (preferably on USB so that it is not
horrendously slow loading apps) and make sure it runs ok on your
machine.
The advantages of upgrading are that you do not need to re-install any
apps that are not included in the default install and any
configuration information and documents will automatically be carried
over into the new release.

A have rarely had any problems upgrading, and if you are already
prepared to re-install then you can go ahead with the upgrade and if
you have problems then you have not lost anything other than a little
time.

A good compromise is to re-install but keep your home directory.  You
can do this by selecting 'Something Else' (or something similar) on
the What Do You Want To Do page and then selecting the partition that
already has Ubuntu on it as '/' but *do not* select Format.  That way
it will install the new version but leave your home folder as it is.
You will keep your configuration and data files and all you will have
to do is to install any non-default apps.
