Yes, current subscribers to Disney Plus, Hulu, or ESPN Plus can upgrade any of their existing subscriptions to the bundle. You just need to sign up for the Disney Bundle using the same email address you have on file for your current membership. Disney will then adjust the bundle cost to account for your existing subscription fees. Keep in mind, however, members who have existing subscriptions through special promotions — like Spotify's Student Plan with Hulu and Showtime — are not eligible for an upgrade to the bundle.
