It is recommended to backup everything before you make any changes, so
that you can restore it if there are problems.<br>
<br>
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.<br>
<br>
Red Hat version 4 uses up2date to do all official updating:
<a class="moz-txt-link-freetext" href="http://linux.die.net/man/8/up2date">http://linux.die.net/man/8/up2date</a><br>
<br>
Red Hat version 5 uses yum: <a class="moz-txt-link-freetext" href="http://linux.die.net/man/8/yum">http://linux.die.net/man/8/yum</a><br>
<br>
You will have to use your best judgement in this case. There is a lot
of help available at <a class="moz-txt-link-freetext" href="http://www.linuxquestions.com">http://www.linuxquestions.com</a> and
<a class="moz-txt-link-freetext" href="http://www.linuxforums.org/forum/">http://www.linuxforums.org/forum/</a> for when you need it.<br>
<br>
Best regards,<br>

Es recomendado a la reserva (backup) todo antes de que usted haga
cualquier cambio, de modo que usted pueda restaurarlo si hay problemas.<br>
<br>
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.<br>
<br>
La versión 4 de RedHat usa up2date para hacer toda la actualización
oficial: <a class="moz-txt-link-freetext" href="http://linux.die.net/man/8/up2date">http://linux.die.net/man/8/up2date</a> <br>
<br>
La versión 5 de RedHat usa yum: <a class="moz-txt-link-freetext" href="http://linux.die.net/man/8/yum">http://linux.die.net/man/8/yum</a> <br>
<br>
Usted tendrá que usar su mejor juicio en este caso. Allí mucho ayuda
disponible en <a class="moz-txt-link-freetext" href="http://www.linuxquestions.com">http://www.linuxquestions.com</a> Y
<a class="moz-txt-link-freetext" href="http://www.linuxforums.org/forum/">http://www.linuxforums.org/forum/</a> para cuando usted lo necesita.<br>
