The Migrate Sharing Insights tab offers a breakdown of all permissions associated to your content (based on the source content). It shows the overall breakdown of how content is shared and the top user and group contributors. You can quickly identify the most shared files and folders. You even have the option to export a full permissions report to view the permissions assigned to each item in the transfer.
The value "Not Shared" represents both items that have no permissions as well as content shared by inheritance from the parent folder. At this time, DryvIQ only tracks permissions applied during transfer, not permissions that result from inheritance within the hierarchy.
