Yes, that would be the transition path. New apps would be v6 only.
Existing apps would be transitioned to v6 only, as soon as that makes sense
The core would be transitioned to IPv6 soon as it makes sense
Hosts would remain dual stack as long as v4 only services need to be reached
- tunnel hosts v4/v6 to a dual stack router/relay
- of course this requires NAT, but hopefully limited ALG support
