I purchased a Bolt from Amazon and will set it up soon, replacing my Premiere. I rad somewhere that I should call Comcast to disconnect the cable card in the Premiere before installing - and then call again to activate it in the Bolt. Is this correct? Is there any way to migrate all my one pass settings from the Premier to the Bolt without doing it manually? I am guessing that I should keep my Premiere connected to my home network (even if not connected to a TV), so that I can watch the shows recorded on it before installing the Bolt. Correct? Any other advice before I start the install?
