copy old shows to bolt

I currently have a tivo premiere and have ordered a bolt for my new 4k TV. What is the best way to copy the content from my old tivo to the new one?

1) can I just swap out the cable cards and make a call to my provider (comcast) to make the switch? Or do I need to get an entirely new cable card?

2) I have a lot of unwatched content stored on my current tivo. is it possible to just copy it over a usb cable or something? If so, is there a tutorial online somewhere? I only have one TV, so I can't just move the old tivo to another room.

Thanks!
