Actually, if you are taking both drives and combining to one, I recommend:

) Remove old drives A & B. Install C. Run builder on C. Install A as a slave drive. Copy A -> C. Install B as a slave. Copy B -> C. Remove B. Delete C's database directory. Reboot / sync.

If you are leaving A in place:

) Remove A & B. Run builder on C. Install C as master, B as slave. Copy B -> C. Install A & C. Wipe database directories, rebuild / sync.

Your milage may vary.
