Harmony TCP migration from IPv4 to IPv6

I currently use Harmony V2.06's TCPIP stack which is configured to work using IPv4. It is modeled after the TCPIP_tcp_server example code. I am now trying to migrate to IPv6. Through the configurator I have additionally enabled IPv6 then generated the code. Also, I have looked at the documentation and tried using the pic32_eth_web_server example without much success. The end goal is to use IPv6 to connect to a separate web application. Could someone provide us with an example of how to do this migration?

    For a server socket it is very simple. Just open the socket with:
    TCPIP_TCP_ServerOpen(IP_ADDRESS_TYPE_ANY, localPort, 0);
    This way it will accept either IPv4 or IPv6 connections.
    The HTTP_NET uses the sockets this way, so if the IPv6 is enabled and you point a browser to the PIC board using an IPv6 address, it should just work without any changes.
