Migration from IPv4 to IPv6 does not mean replacing IPv4 with IPv6 but, instead, enabling IPv6 in addition to IPv4. This allows network-administrators to start benefiting from this new protocol.

One of the challenges involved for the network administrator in migrating to IPv6 is quantifying the effort and costs of an IPv6 migration, as well as planning how to approach the task. Migration over to IPv6 is not simple, and requires a solid and transparent process. However, with proper IP Address Management (IPAM) tools, and information on the existing IPv4 infrastructure, the effort becomes manageable.
