Export an organizational hierarchy To update an existing organizational hierarchy, you can export it to a CSV file, make updates, and then import the file. Log in to the BlackBerry AtHoc management system as an administrator. In the navigation bar, click Users > User Attributes. On the User Attributes screen, find and click the Organizational Hierarchy attribute. On the Organizational Hierarchy screen, in the Values section, click Export to CSV. Any changes you make to the organizational hierarchy must be saved before you export the organizational hierarchy. A CSV file containing the organizational hierarchy is downloaded to your local computer.
