That was what made me throw caution to the wind and attempt a Time Machine-assisted swap. The good news is, it works as billed. You get a bit-for-bit transfer to the virgin drive with minimal fuss. The bad news is, if you don't use a little trick we discovered today, you probably won't get it to work at all.
