Move contents of Roamio drive directly onto larger drive?

Hi - I read that you can upgrade a Roamio by just dropping in a larger drive. I also read that you can move your programs off the old drive to a PC and then after the uprgrade move them back to the new one. But I was wondering if it was easy/possible to upgrade in place. Pull the 500GB drive, move it's contents to a 2TB drive, and then put the 2TB drive into the unit. Or is this not straightforward?

Thanks!
