What is an appropriate action to take regarding table migration during the DMO procedure?

Ensuring that tables have optimal sequencing during the Data Migration Option (DMO) procedure is crucial for effective data transfer and system performance. Proper sequencing helps in maintaining data integrity and reduces potential errors that might arise from dependencies between tables. For example, if certain tables depend on the data from others, migrating them in the right order minimizes the risk of encountering integrity constraints during the migration process. This approach not only streamlines the migration but also leads to faster processing times, as a well-structured sequence can leverage parallel processing capabilities of the HANA system, optimizing overall performance.

Other options, while they might have relevance in certain contexts, do not directly address the critical nature of sequencing in the DMO process. Limiting the number of migrated tables could lead to incomplete data transfer, aggregating similar tables might not address necessary relational dependencies, and restarting the system post-migration, while sometimes necessary for application stability, does not inherently improve the migration process itself. Thus, focusing on the optimal sequencing of tables ensures a smooth and efficient migration.
