How do I convince management to approve IPv6 deployment?

Kedare asked:

I currently have the idea to deploy IPv6 on the corporate network of my enterprise. But my boss (CIO) asked me what the benefits are? And I did not have an answer.

Hurricane Electric has a management-level presentation The Business Case for IPv6 which you may find helpful.

It’s a bit dated, but still useful: eweek’s How to Build a Business Case for IPv6.

You can find much more from an Internet search.
