I have thread in the Productstream NG about going from Vault to Productstream that I would really like some insite from Autodesk on. I have gotten no reply from anyone at ADSK on that thread so I am posting a link to it here hoping it will be seen. I am at a stand still in my deployment until I understand where to go.
