The correct response is to verify session messages to ensure that no new write operations are occurring. This action is crucial because during a data migration process, it is important to maintain data integrity and consistency. If there are ongoing write operations while the migration is taking place, it could lead to a situation where the migrated data does not accurately represent the state of the database at the time of migration.

By verifying session messages, you can confirm that no active connections are attempting to alter data in the source instance database, allowing for a clean and accurate migration. This step assures that the data captured during the migration reflects the final state of the source database, minimizing the risk of data loss or corruption due to ongoing changes.

In contrast, proceeding with the migration regardless of the session status could result in inconsistencies in the migrated data. Deleting user accounts connected to the source database without verifying the status could lead to potential loss of important data or permissions needed post-migration. Restarting the source database may cause unnecessary downtime and does not address the potential issues arising from unverified session activity.
