  This paper presents the features and benefits of legacy IPv4 network
migration towards major two latest networking paradigms viz. Internet protocol
version 6 (IPv6) and the software-defined networking (SDN). These latest
networking paradigms are the enabler of future generation networking so that
the standards and requirements of fifth generation (5G) wireless networking can
be achieved. Features and migration approaches of IPv6 and SDN will be
separately discussed, then a joint migration approach of SDN and IPv6 network
termed as SoDIP6 network migration will be presented, and the integration of
SoDIP6 network as a backbone of 5G network will be introduced.
