Answer for a generic "I need to do this BIG work on my IMPORTANT server" question. The strategy I tend to use for big upgrades for servers with vital functions is to use a replacement server while doing it, that is: *) create a compleete full backup of your server ( or use the latest regular ). *) do a compleete restore on a replacement server ( not having it connected. ) *) Test functionality thoroughly. *) Do a quick switch with the network cable. *) Now you can Upgrade without risking anything, and You also can Test functionality in a way you couldn't do else. *) Last, switch back the network conections. *) Keep the temporary replacement computer in case sotehin goes wrong, for a while. -- Christer V O Y A G E R <voyager001@usa.net> writes: > I want to ask how one we can upgrade his system from RedHat 6.0 to Redhat > 7.0. > > If any one reboot the system, start installation of Redhat 7.0 and select > Upgrade and then installs the dresired packges then during this period of time > that system will not be available on the internet.
