When reviewing a migration of a data warehouse from a legacy system to a different architecture in the cloud, the IS auditor should prioritize concerns that have the greatest potential impact on data integrity, security, and overall system performance. The most significant concern is related to data quality and integrity. If the data was not cleansed before being moved from the source to the cloud data warehouse, it can lead to inaccuracies, inconsistencies, and potential corruption of data, which can undermine the reliability and effectiveness of the entire data warehouse. Therefore, the greatest concern is that the data was not cleansed before moving to the cloud data warehouse.
When reviewing a migration of a data warehouse from a legacy system to a different architecture in the cloud, the IS auditor should focus on aspects that have the greatest potential impact on data integrity, security, and overall system performance. Among the given options, the GREATEST concern is typically related to data quality and integrity, as this can have significant repercussions on the effectiveness and reliability of the data warehouse. Therefore, option D, "The data was not cleansed before moving from the source to the cloud data warehouse," is the most significant concern for the IS auditor. In summary, while all the options may be concerns to some extent, data quality and integrity (option D) typically have the most significant impact on the success of a data warehouse migration project.
Data can be cleansed after the migration, the bigger concern here that should be addressed is the increased latency of synchronization
