Re: [v6ops] Draft on DC migration to IPv6

Diego,

	Some questions and comments.

	The maturity level 1 is a bit odd to me. Do you mean that it is common to DC to translate all the traffic from v4 to v6 in the border? I am misunderstanding something?

	Shouldn't be a dual stack network (with servers and services in v4) a maturity level 0.5 or 1.5?

	I think also that there are some common scenarios not explored here, for example some native dual stack servers and services combined with single stack services (web server in DS + database server in v4 only).

	The maturity level 3 I think that you need to add that a single stack network is much simple to manage than a dual stack one. IMHO that will be the killer app for an IPv6 only DC.

	Also, take a look at draft-ietf-v6ops-icp-guidance, there is some content that it is already there. 

Regards,
as
