Migrate / Restore Fedora on different hardware

[Roland Venter]

Has anyone succeeded in migrating Fedora / RH onto a different hardware 
platform?

Scenario:
If got a full tar backup of an existing running server.  I want to restore a 
working version on another box, but with diferent hardware (RAID, NIC's, 
etc). Restoring the user data is easy.  I need to know what files not to 
overwrite during the restore after a minimal install on the new box.

I've identified some files needed:
/boot/grub/grub.conf
/boot/grub/device.map
/etc/sysconfig/rawdevices
/etc/sysconfig/hwconf
/etc/sysconfig/grub


Any got suggestions or links?
