When migrating from an IPv4 addressing scheme to an IPv6 scheme, the following three approaches are commonly used:
1. **Enable dual-stack routing**: This approach allows both IPv4 and IPv6 to be run simultaneously on the same network. Devices can communicate using either protocol, providing a seamless transition as parts of the network move to IPv6.
2. **Configure IPv4 tunnels between IPv6 islands**: Tunneling allows IPv6 packets to be transmitted over an IPv4 infrastructure. This is particularly useful when connecting isolated IPv6 networks (islands) over an existing IPv4 network.
3. **Use proxying and translation to translate IPv6 packets into IPv4 packets**: This method involves using translation mechanisms like NAT64/DNS64, which allows IPv6-only devices to communicate with IPv4 resources by translating address formats and protocols.
Therefore, the correct answers are:
- Enable dual-stack routing
- Configure IPv4 tunnels between IPv6 islands
- Use proxying and translation to translate IPv6 packets into IPv4 packets
