There may be new hardware on the machine that you will have to configure or modify your kernel to use, but for the most part, you can move from system to system with a reasonable assurance that the system will boot and detect the majority of the hardware in it. Case 2) You are running a KERNEL is which you stripped out every bit of hardware that you do not have. In this case, it's fairly easy to find hardware that you won't even boot on, especially if you are changing processor families, or moving SMP installations to single cpu installations. Your best bet here is to reinstall the GENERIC kernel on the machines before backing them up, then boot GENERIC on the new machine, reconfigure a new kernel and build/install that. As far as your specific case of moving to multiple pci bus hardware, I don't have any direct experience with doing something like that, but I don't know of any reason for that to not work as is.
