It was so promising in a document but not in real use so far
first there is a bug on aggregate selection page, not a major issue but it's there anyway. If you try to play with manual selection mark you will found out
but the real case i face is that available interface list come from default-ipspace, not any other existing one, what I have not try yet is that create interface there but
not assign it correct IPSPACE or create IPSPACE to destaination storage at all. I don't know if it will make migration then possible but dosen't sound so working
way to me.
Anyone ideas how this shuld work not just with multistore but in multitenant environment, thanks for answers
