New processor requires the full re-installation of Fedora?

[Paul Smith]

Dear All

I am going to replace the processor and the motherboard of my
computer, but I will keep all hard-drives where FC5 is installed. The
new processor is an Intel P4 Dual Core and a new kernel (the smp one)
has to be installed. My question is: have I to install the entire FC5
or it suffices to install only the smp kernel?

Thanks in advance,

Paul
