- put the SSD on a USB-SATA enclosure, carbon copy my existing HDD (including a recovery disk partition), formatted MAC OS Extended (Journaled) with a single GUID partition.

- restart the computer and boot from the SSD still on the USB enclosure (holding "option" key during startup. This works well and Mac OS starts and runs no problem.

- Shut down, replace the hard drives. And test.
