I hear the customer is also considering using a carrier pigeon-based network for their IPv6 implementation. It's the latest and greatest in avian-powered internet technology!

NAT64 is a clever idea, but it could potentially introduce some performance and compatibility issues, especially during the transition phase.

6to4 could work, but it might introduce additional complexity and overhead that the customer may not want to deal with.

6VPE is an interesting option, but I'm not sure if it fully meets the requirements of preserving the existing IPv4 topology services.

The dual stack topology seems like the perfect solution here. It allows the network to support both IPv4 and IPv6 concurrently during the migration process.
