I'm constantly surprised how many people wish to 'upgrade'.

Historically I've been updating my Linux distro when Redhat still was
shipped in nappies.  I've learnt pretty early on the following:

1. Never trust an OS upgrader... it always is like a dog with diarrhea
running through your house.  :(
2. Keep seperated partitions...   /home /usr/local  and normally the
ones you wish to keep...  (I also backup the entire /etc directory)
3. Ensure you have working backups... well of at least the stuff you
MUST get back.
4. Choose to install fresh (not upgrade), and format the existing
partitions /, /usr, /tmp and /var....  whilst you probably wish to
keep /usr/local and /home.
5. Recover anything you need (such as /etc based files).


You'll be up and running much faster... without the mess.  ;)
