If you use your existing Roku account, any app you have installed on your Roku device already linked to your account will be downloaded and installed on the new device automatically.
More specifically, what is the model number of your Express, and which Ultra model did you get?

I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
