Hi Sirs,
I am having the same problem. Our customer has thousands of 3D models in CC Library, motors, threads, etc,... personalized.
After migrating, CC doesn't runs well. I'm thinking in having a normal folder inside project path that no cause us more migrating problems.
The idea of content center is genial, the performance is poor. (Have you tried an update a family of iparts? It is a hell).
