upgrading a live server without rebooting

[Stefano Tabacchiera <s tabacchiera gruppocsf com>]

Hi there,
is it possibile, by only using rpm -Uvh --somethingIDontKnow *.rpm,
to upgrade remotely (by ssh) a whole RH7.1--->RH7.3 live server??
I can't reboot the server and upgrade using Kickstart from a RH boot cd.
I'm on ssh, so I need to do this while the server is up and running.
I can put the server in single mode. Not more than this.

Anyway, my problem is:
when I try to simply issuing rpm -Uvh *.rpm, it complains about some missing 
files/failed dependencies. I don't want to install *everything*, but just 
upgrading the existing packages.

Tips are welcome.
Thanks all.
