Greetings.

I have a Redhat 7.2 router/firewall with no services from the Internet running. I am thinking of upgrading to Redhat 9.0 but am unsure of how to upgrade.

I have downloaded the Redhat 9 CD and I would like to upgrade only the installed rpm's all at once. Is there a command that does this

BTW.there is no graphic server running

Thanks for your help

Hi,

You want 'rpm -Fvh' which will only upgrade packages that are already installed. You probably don't want to do this for the kernel though. There might be an "except" switch, look at 'man rpm', but if not and if you have the space, you could create a directory on your hard disk and copy over all the rpm's except the kernel-related ones and maybe anything else critical.

That way you can have a new and old version of these packages until you're sure the new version don't cause you any problems.

There might be some new packages you will need, not sure how the '-F' (freshen) switch handles these. You can use '--test' for a dry run.

Is there some reason you don't want to upgrade from the installer? I'm 99% sure there is an option to upgrade from a previous version. In fact, I'm sure there is.

Thanks folks.I think that I will install from the installer.

Thanks for your responses

Cheers
