The Wally has no internal hard drive, so the recordings are already on the external drive.
You can transfer the entire drive from one Wally to another. Other than that, there is nowhere to transfer the recordings to, for the reason I stated above.
To be technical, there is a way to hook both hard drives up to a computer to transfer files from one drive to another, but that might be a more involved process than the average subscriber would be willing to fool with. I suppose you could just clone the entire hard drive to have access to recordings from the same Wally on both Wally at the same time.
You are 100% correct. Forgot we are talking the Wally not a VIP.
