I'm upgrading from a Premiere to a Premiere 4. Is it possible to transfer or clone my hard drive and put it in the new TiVo so I don't lose all my recordings and thumbs info? I'm pretty comfortable with cloning/upgrading a hard drive for use in the same TiVo, but I've never needed to transfer one to a new TiVo. Specifically I have a Premiere with a self-upgraded 1 TB drive, and I'm upgrading to a Premiere 4 along with a new 2 TB drive. So I've got a lot of things going on and not sure what's possible and in what order things need to be done. Any help is appreciated!
