UPDATE:
For users looking to transfer their subscriptions from one hub to another, please check out this post:
It's not currently possible to transfer a subscription from one hub to another. Hub Protect is an extended warranty service for the specific hardware. For extended warranty claims, the subscription service is transferred to the new hub when the replacement hub ships. We have helped some users in the past transfer the service from one hub to another. As mentioned above, the best way is to open a subscription case by submitting the form on the following page (select "Other" as the option). You could also send me a private message with your hub's MAC address.
