Explanation:
During the data conversion stage of a project, the data owner is primarily responsible for reviewing and signing-off that the data are migrated completely, accurately and are valid. An IS auditor is not responsible for reviewing and signing-off on the accuracy of the converted data. However, an IS auditor should ensure that there is a review and sign-off by the data owner during the data conversion stage of the project. A database administrator’s primary responsibility is to maintain the integrity of the database and make the database available to users. A database administrator is not responsible for reviewing migrated data. A project manager provides day-to- day management and leadership of the project, but is not responsible for the accuracy and integrity of the data.
