How can data loss during migration be minimized?

Conducting thorough backups and verification before full-scale migration is crucial for minimizing data loss during the migration process. This practice ensures that all data is securely copied and can be restored if anything goes wrong during the actual migration. By having a reliable backup, data integrity is maintained, providing an assurance that users can revert to the pre-migration state if necessary. Additionally, verification involves checking that the backup has been completed successfully and that the data is intact and usable, further mitigating the risk of data loss when moving to a new system.

Other options, while they may seem relevant, do not effectively address data loss concerns. For instance, performing updates during peak hours can create network congestion and increase the risk of interruptions, potentially leading to data inconsistency. Using only one migration tool might limit the efficiency and capabilities available for the migration process, as different tools can be optimized for various tasks or types of data. Finally, restricting user access during migration could help reduce the risk of conflicts, but it does not directly prevent data loss; it merely minimizes the chance of user-induced errors.
