[Andrew Cross]"For him to be able to work on the project is all I need to do to Media Manage the clips onto the hard-drive?"
ALL 16TB worth? What will he store that on? You can use the Media Manager to RECOMPRESS to a smaller bit rate format, like ProRes proxy...but the files might still take up more room than is really portable. Offline RT possibly. But with that much footage, that'll take days.
[Andrew Cross]"Will there be any reconnections issues?"
If you use ProREs Proxy...no, just reconnect to the full res originals. If you recompress to offline RT, the frame size is a lot different, so you will have to adjust for this when you reconnect.
