If Cisco could be bothered to put the exact error-message in to the bug "Description" then there is a chance others might find it with a (Google) search; I wasted 8 hours due to sloppy coding! Yes, I made a mistake not enabling ACS Import, but I never got 'round to looking for that due to the complete spurious error-message.
Here is the message, in the hope it gets indexed and becomes searchable:
This ISE version is not supported. Migration tool will now abort.
Not supported, indeed!
