Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
If you mean re-add all your channels? No. If the new tv uses a different IR code set then the old, you would need to reprogram it for the new tv. Just go into settings> remote & devices> remote in use> program tv
