My way:
- Boot with a live cd with clonezilla on it (i.e. clonezilla live)
- clone the complete harddrive to the new one. Pay attentention, that the new one must be equal or bigger than the source.
- Use another live cd with gparted on it and move or resize the partitions.
Second way (more work and more complicated):
- Boot with a linux live system (debian live, Knoppix whatever)
- mount the old one to a new mountpoint in root, like /disk1
- partition the new drive to your needs manually
- mount the new one to a new mountpoint in root, like /disk2
- use rsync for transferring data to the new one
- reboot to your old system with the connected new harddrive
- install grub on the new harddrive (grub --install /dev/sdb or update-grub might do it)
Have fun
