I've never done it myself, but I asked a really experienced systems manager about the same thing: Use mdadm to create software- raids on the new(!) harddisk with raid-level 1 and just 1 disk per raid and copy all the data form your old to your new disk. Then install grub on the new disk, shutdown your box and switch the disks on the buses (or try starting the system with just the new one). Your system should boot the new disk (don't forget to set grub and fstab to use your raid as root- partition) If all comes up alright, erase the old disk and hotadd the now empty partitions to the raids. This should do the job. :-) But Ir would really advise you to start and test your system with just the new disk, leaving the old one outside. And be aware that you should backup your data before this operation and don't hesitate to ask, if anything is unclear. Otherwise you could destroy your system.
