"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

By default there was no way to export IAS settings to NPS - but MS cooked up a hotfix that will allow the export of IAS settings to NPS servers, outlined as follows:
Export IAS config from 2003 server with IasMigReader.exe and import it on 2012 NPS with Netsh

Register 2012 NPS with active directory
