It is recommended to backup everything before you make any changes, so
that you can restore it if there are problems.

Mostly, Red Hat takes care to not allow changes that will "break"
existing servers. If you mean to install a version that is not from Red
Hat, you will not be able to call on Red Hat support for help, even if
you have a support contract.

Red Hat version 4 uses up2date to do all official updating:
http://linux.die.net/man/8/up2date

Red Hat version 5 uses yum: http://linux.die.net/man/8/yum

You will have to use your best judgement in this case. There is a lot of
help available at http://www.linuxquestions.com and
http://www.linuxforums.org/forum/ for when you need it.

Best regards,

- Paul



Es recomendado a la reserva (backup) todo antes de que usted haga
cualquier cambio, de modo que usted pueda restaurarlo si hay problemas.

Sobre todo, el RedHat tiene cuidado no para permitir cambios que
"romperán" a servidores existentes. Si usted piensa instalar una versión
que no es del Sombrero Rojo, usted no será capaz de visitar el apoyo de
Sombrero Rojo a la ayuda, aun si usted tiene un contrato de apoyo.

La versión 4 de RedHat usa up2date para hacer toda la actualización
oficial: http://linux.die.net/man/8/up2date

La versión 5 de RedHat usa yum: http://linux.die.net/man/8/yum

Usted tendrá que usar su mejor juicio en este caso. Allí mucho ayuda
disponible en http://www.linuxquestions.com Y
http://www.linuxforums.org/forum/ para cuando usted lo necesita.

Recuerdos,

- Paul
