In one embodiment, a network device in a network obtains information identifying first storage and second storage. The network device notifies one or more other network devices in the network that traffic that is received by the other network devices is to be routed to the network device. The network device performs data migration from the first storage to the second storage. When the data migration from the first storage to the second storage is completed, the network device notifies the other network devices in the network that traffic that is received by the other network devices is no longer to be routed to the network device.
