We see the original version has Milan and v1 of the same alias currently

It now knows about v2.
As Markus mentioned, there will be further changes to add v3/v4 in the future, 
but that should being the situation forward a bit without resetting it all.

This is already verifying the testcase, but let me also ask @Markus do you have 
a Milan system at hand to see if the Milan-v2 here works as expected on the 
real system?
I have not looked in our HW pool if I could have access to one and you might 
likely have that more easily - do you?
