I have come to know about SailPoint Migration Tool during Navigate, London. I don’t think it is available for Public. You can check your CSM.
This migration tool will give you insights about your IIQ configurations, some analysis, not like migrating config from IIQ to IDN automatically.
If you have good knowledge on both IIQ and IDN products, then migration is no big deal. It is not about migrating every work you did in IIQ to IDN, some are not required even. For example LCM workflows, you can forget them.
IDN supports <20 Rules, where as IIQ has ~200 Rules. So, most of the Rules will be converted to Transforms.
You can use same IQ service from IIQ, no changes required.
