 ### Ensure the segments of each blob path are named
 
 The migration process creates a directory for each path segment of a blob. Data Lake Storage directories must have a name so for migration to succeed, each path segment in a virtual directory must have a name. The same requirement is true for segments that are named only with a space character. If any path segments are either unnamed (`//`) or named only with a space character (`_`), then before you proceed with the migration, you must copy those blobs to a new path that is compatible with these naming requirements.
