I have installed Red Hat Linux 9.0 on a PC dual processor and my kerner version is kernel-smp-2.4.20-28.9smp. I have configured sendmail service, http(s) service, and dns server. As soon as on April 2004 RHL will be not more available and the prices of Red Hat Enterprise is high, I have decided to try Fedora using the distribution enclose on Red Hat Magazine. My question are: Can upgrade my old system using Fedora CD-rom and I will mantain also the configuration of sendmail, httpd, dns ? Thanks for help and suggestions Fabrizio Nozza
