Replacing Old Roku 3 With Newer 4k Unit

Hi tribaltat,

Congrats on your first post in the Roku Community!

We can certainly understand your concern about setting up a new Roku device to your existing Roku account. We will do our best to assist you with your inquiry.

When you link multiple or new Roku devices to a single Roku account, the channels and purchases will be the same on each device. When a channel is added or removed on one device, the channel is automatically added or removed on all devices linked to that account that support the channel, as well as the preferences and account settings.

In regards to your existing subscription, some channels automatically sign you in, most channels require you to sign in to access your paid content. The email and password you use to sign in to a channel depending on how you signed up for it. 

We would recommend taking a look at our Support page for more information regarding How to add a Roku® streaming device to your Roku account | Official Roku Support

We hope we have addressed your question appropriately, but please don't hesitate to let us know if you have any questions or additional feedback.


Best regards,
Mary
