Skip the transitions with IPv6-only data center deployment
Before Tore Anderson, the rock star behind the IPv6-only data center, started explaining the interesting details of his ideas, I did a short intro explaining the need for IPv4+IPv6 access to your content and the steps you have to take to get there.
You might decide to proceed down the more traditional path (doing 5-6 transitions in the next few years) or deploy IPv6-only data center and be done with it.
