Migrating hard drive contents with R&R

[bri]

i want to move all my hard drive contents from a X61 to X61s with a bigger hard drive. is this possible with Rescue & Recovery? will one of these work:

plan A:
backup X61 to USB hard drive
connect USB hard drive to X61s
use R&R on X61s to restore contents

plan B:
backup X61 to USB hard drive
swap in X61s hard drive to X61
boot X61 to R&R desktop
restore contents to X61s hard drive
