Switch from Premiere to Roamio

I currently use a Tivo Premiere but recently bought a Roamio which I have not yet activated. I had planned to activate it when I move to a new address since I thought a Comcast installer would be coming out, however I just found out that they will not need to send an installer to activate me at the new address. So my question is, do I simply take the cable card from the Premiere and put it in the Roamio and follow the instructions? When I first got the Premiere it was required that an installer come to put the cable card in..
