A system for virtual internet protocol (VIP) address migration. The system comprises serving one or more clients connected via a switch router over a network to one or more network gateways. The switch router forwards packets to the VIP address of a first network gateway. If the first network gateway determines a VIP address migration criteria has been reached, the first network gateway may migrate any new traffic associated with a packet flow over to a second network gateway for more efficient processing by inserting a default flow code into the header of the VIP address of the packet. Older packets continue to process on the first network gateway, however new packets are forwarded and processed on the second network gateway. Once the packets being processed on the first network gateway completes, the second network gateway becomes the default network gateway for processing existing and new packets.
