I've done this a couple of times in the past with various Linux flavours. Basically the approach I took was:
1. Mirror the physical disk layout on virtual disks - usually done using a live boot CD and a USB->IDE thingy in various arrangements.
2. Finagle the boot manager config to match any changed disk names or set UUIDs on volume etc so it all matches-up.
3. Reinstall the bootloader (GRUB or LiLo). It can be a drag if you don't have just the right version of GRUB sometimes.
4. Boot it up and cross fingers.
5. If it doesn't work, see what went wrong, attempt to fix and retry.
Not very scientific, but you get there in the end.
It's best if you can operate from a nonvolatile backup of your live system just so you don't break anything too badly.
