I have two S2 240 Tivos. One has been upgraded to a 200 Gb hard disk, the other has its original 80 GB hard disk. The new Lifetime transfer offer only applies to the older, upgraded S2, unfortunately. The other one is also lifetime, but too new to qualify. So, my question is: Can I swap the hard disks on these two TiVos without major pain? I'd love to upgrade to the new dual tuner model, but don't want to lose my big hard disk with all it has stored on it.
