moving linux hdd from one system to another


I will be doing the following to see if I can come up with a recovery procedure.

I will be installing RH9 on a system. The actual specs are not really relavant, but for argument sake, it will be a single P4 system with a fairly basic hardware config. I will then remove the Hard Drive containing the Linux os, and placing it in a completely different system. The hardware on the other system is considerably different. It will be a dual Xeon system with many different hardware components.

Now, I do not expect Linux to boot without any problems. Obviously, all of the new hardware in the system is going to cause a ton of grief. In fact, I donít expect Linux to even boot at all.

The reason Iím doing this is because I will be building a new server soon with completely different specs. I will then want to move my hard drive from the old machine to the new one with all of the new and different hardware. I figure I should practice this before trying to do it on my actual file server.

Any help is appreciated.

you can keep a lot of your previous linux os. relevant things are your network configuration (number of cards), compiled for machine-arch-depended software and things like lilo/grub, optimizations(elvtune/sysctl/..).
the only thing apart is to build a new kernel for your new machine (fitting to your new hardware) and get lilo/grub/!BIOS boot from the right drive.
i've done that a couple of times now (ex. p66>p133>pii300 with a little box at home) and it worked without much trouble.

since you're going to use multiple processors (and i don't have any expirience with this issue) it might be better to set up the machine from the scratch. this will give you the possibility to optimize your programms for smp.
