The migration path, clearly, is "support both". That's trivial if they
are using different ports, although less so if IKEv2 stays on UDP/500.
There is no way to require the two *protocols* to be interchangeable
without sacrificing most of the benefits we hope to see from IKEv2. But
it is implementations, not protocols, which interoperate.
