Steps
Retrieve the active operational dataset (network name, network key, extended PAN ID, channel, mesh-local prefix) from the existing border router.
On the OpenThread Border Router (OTBR) REST API, GET /node/dataset/active to read the current credentials.
Apply the same operational dataset to the new border router, either via its REST API's pending dataset endpoint or the ecosystem's Thread credential-sharing API.
Bring the new border router onto the same Thread network using the shared dataset rather than forming a new network.
Confirm both border routers appear as active routers on the same Thread partition, so if one goes offline, devices route through the other.
Known gotchas
Forming a brand-new network on the second border router instead of joining with the shared dataset creates a separate, incompatible Thread partition.
Thread 1.4 vendor ecosystem credential-sharing APIs are what most consumer border routers use in practice rather than manual REST calls; the raw REST API path is mainly for OTBR-based DIY setups.
