Abstract: Embodiments described herein involve appliance migration. Embodiments include connecting, by a second appliance that is configured to perform a service, to a first uplink and a first downlink of a first appliance that is configured to perform the service. Embodiments include connecting, by the second appliance, to a first endpoint and a second endpoint to which the first appliance is connected. Embodiments include determining, by the second appliance, existing flows processed by the first appliance. Embodiments include processing, by the second appliance, a plurality of packets received via the first endpoint by: forwarding, by the second appliance, first packets of the plurality of packets that correspond to the existing flows to the first appliance; and performing, by the second appliance, the service for second packets of the plurality of packets that do not correspond to the existing flows.
