Hey there,
Migrating from IPv4 to IPv6
Migrating doesn’t mean replacing IPv4 with IPv6. It just means enabling the IPv6 along with IPv4.
In the current scenario, most organizations rely on IPv4. For them, it is practically impossible to migrate to IPv6 in a day. This means that for some time, both will coexist.
There are several techniques for migrating from IPv4 to IPv6. Some of them are as follows:
Dual-Stack: In this technique, the network devices are configured for both the versions of IP.
Tunneling: This technique involves encapsulating one protocol inside the other. For example, if you have two devices using IPv6 connected with the IPv4 network, then the traffic is tunneled inside the IPv4 packets and sent over the network.
Translation: Translation involves translating one protocol to the other. This allows IPv6 hosts to communicate with IPv4 hosts.

Hope this help.
