OS Upgradation

Can anybody give me some useful links to know about OS upgradation using installer.

Thanks & Regards

which distro? do you mean updating the software on it or the whole OS to another version?

I am using Fedora Core 3 Distro.

I need to know how the OS is upgraded / repaired using installer(Anaconda etc).
Is there any software available for this? If so how is it done ?
I need to know about how the kernel or any firmware is upgraded without loosing data during installation.


Thanks & Regards

it is done using yum,yumex, apt and synaptic. (at least thats what fc4 uses).

installing software in fc4 is a pain in the butt.
