I plan on migrating data from my present Mac Pro to the new iMac 5K Retina when the new machine arrives using Target Disk Mode.. The MP has four internal drives:

Bay 1: Time Machine backup
Bay 2: Storage drive for large files (at this time, redundant)
Bay 3: My default startup drive with OS 10.6.8
Bay 4: Clone of Bay 3.

When I start up in TDM, which drive will Setup Assistant in the new iMac see? I want to migrate from Bay 3.
