In a Shuttle Transfer Report, items marked as "Partial Success" do not have their file sizes aggregated under the "New Size" category which indicates the total amount of data transferred during that migration job run. This can lead to a seemingly large discrepancy between the job Total Size and the amount of content which was successfully transferred.

Such "Partial Success" items ARE successfully uploaded to Box, but certain file details (e.g. original last modifier) may not have been successfully set in Box. The lack of this file metadata does not change the fact that the files themselves made it to Box. Their file size should therefore be included in the aggregated New Size category to better reflect the total amount of data which was successfully transferred to Box.
