Hardware Upgrades and Reinstalling Fedora Core 4

[Robert L Cochran]

Hi, I am getting a new hard drive, motherboard, and processor. I'm 
moving from a single-core Athlon 64 chip to a dual core Ahlon 64 chip. 
My current machine has Fedora Core 4. The hard disk partitions look like 
this:

[rlc at bobcp4 ~]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       29G   18G  9.7G  65% /
/dev/sda2             289M   38M  236M  14% /boot
none                 1004M     0 1004M   0% /dev/shm
/dev/sdb2             109G   40G   64G  39% /mnt/any

There are 2 physical hard drives on my machine. The first is a 60 Gb 
drive with partitions for Fedora Core 4 and Windows XP. The second is a 
120 Gb drive which is mounted on /mnt/any. I want to use a brand new, 
much faster 400 Gb drive as sda.

What makes more sense: back up my current /home partition, replace the 
motherboard, drive, and processor, then reinstall Fedora Core 4 from the 
install DVD (which would detect the new CPU and load an smp kernel) to 
the 400 Gb drive and update it with yum, then copy the important stuff 
from my backup of /home?

or

partition the new drive and copy / and /boot to it and switch drives?


Thanks for any advice you can offer.
