Your box can save its apps, settings and favorites to a USB drive, then restore them later.
Insert a USB drive, open the Live TV menu (3-line menu) and choose Backup / Restore.
Note: restoring will not push your favorites onto a server that's already set up on the new box — connect to one of the restored servers to see them. Most USB drives and 128GB SD cards work; some unusual card sizes may not be recognized.
