When I got mine transferred, I sent my request to the other state's caa, and then they requested my exam info from Norway-CAA themselves. That worked.
If you contact Norway-CAA directly I've heard it will depend on which person you talk to. A lot of people have been able to transfer their exams, so don't give up just because you get a no from someone. These days the cost of doing the flying portion of the conversion in Norway is insane.
