query for upgrading from rh7.3 to rh9
Hello mates,
Another newbie here..I have installed redhat linux 7.3 and i am running firewall,router, and web and ftp services on it, It is serving as the gateway to my local area network. I want to upgrade the system to redhat linux 9 by not disturbing any of the installed services or data on the computer so that i do not have to reconfigure my firewall, router,web and ftp services . I'd like to know if i can upgrade in such a manner by keeping my current configuration unchanged.
Thanks in advance
