Scared of "yum update" on old FC4 :-)
I have a Linux server running, it's on Fedora Core 4.
I'm really more a Linux user than a Linux admin, and so last year I installed FC4 with multiple software packages (cvs, phpMyAdmin, mysql, etc...) to help me with web development.
I realize now that Fedora is a project that evolves fast : I just read that FC5 has just been retired, and FC8 is being developed...
I'm a bit worried that my FC4 installation might be prone to attack, as I haven't been updating it for the past year. For all I know, it might even be compromised as we speak :-)
I thought of using "yum update" to update everything, but I'm really scared that this will make some of my installed software not work anymore.
Should I be scared ?
Also, is there any easy way to make my FC4 installation into an FC6 or FC7 installation without disrupting installed software ?
