I agree with others that this is a very hard thing to estimate.

I will say that we run our dual-stack network (fully deployed since ca. 
2012) with exactly the same staffing levels, and actually a slight 
reduction in our recurrent budget, as our older IPv4-only network.

I don't think our network is any less reliable, or suffers a higher 
level of incidents. This suggests to me that, in our case, IPv6 has 
added a very low operational cost. Our incidence of IPv6-related 
problems, particularly rogue RA from machines configured for connection 
sharing, has actually *decreased* substantially since we deployed native 
IPv6.

I don't believe the rollout cost was high. We used refresh cycles to 
upgrade to v6-capable gear, and rolled out slowly to grow our team 
knowledge. But we don't have detailed cost breakdowns.
