[tex-live] Updating with a new version

[Peter Flynn]

I just installed TL2004 on a new server when it occurred to 
me I should really have used the 2005 ISO. Duh.

Is there an "upgrade" option anywhere, or should I just install it and
give the same setup info, or should I try
to wipe the 2004 installation and redo from scratch?

Would this be enough for a complete wipe (given that I asked for
the soft links):

for f in /usr/TeX/bin/i386-linux; do rm -f /usr/local/bin/$f; done
rm -rf /usr/TeX 

Or is there stuff installed in other directories?
