Although Enphase recommends against it I believe (mixing generations at this time), in theory you need one ACCP, two Envoys (one of each type), and you can aggregate into a single portal system (just add the second Envoy to the activation). I think the mixing of systems is not recommended due to potential communication interference.
>From what I understand they are launching an IQ Envoy that will handle both systems in the future, but they are not there yet. I'm actually sourcing some M250's at this moment to add to a M215 system for a client. I wanted to avoid the whole IQ issue and let someone else be the guinea pig, so let us know what results you have! :) We are about to have hundreds of homes with a mix of some with M series and some with IQ series in very close proximity. This should be interesting! But I don't expect any major issues home to home. The first IQ systems are not showing any issues yet.
