What is the purpose of the "Migration Batch" feature in Exchange?

The "Migration Batch" feature in Exchange is specifically designed to organize and execute the migration of multiple mailboxes, making it a powerful tool during the process of moving from on-premises Exchange servers to Exchange Online or between different versions of Exchange. By grouping mailboxes into batches, administrators can manage the process more efficiently, monitoring the progress and handling any issues that arise during migration more effectively.

This feature allows for greater control over the migration timeline, as different batches can be scheduled to run at different times to minimize disruption. It also supports the ability to pause, resume, or complete batches as needed. This structured approach helps ensure that the migration is seamless and minimizes the impact on users.

Other options do not align with the primary function of the Migration Batch feature. The backup process, archiving, and synchronization between on-premises and cloud environments involve different methods and tools that are outside the scope of what Migration Batches are designed to do. Therefore, organizing and executing the migration of multiple mailboxes accurately reflects the purpose of this feature.
