Implementing a Hybrid and Secure Messaging Platform (legacy) — Question 25

Your company has a Microsoft Exchange Server 2019 hybrid deployment.
The company has a finance department.
You need to move all the on-premises mailboxes of the finance department to Exchange Online. The bulk of the move operation must occur during a weekend when the company's Internet traffic is lowest. The move must then be finalized the following Monday. The solution must minimize disruption to end users.
What should you do first?

Answer options

• A. Run the New-MigrationBatch cmdlet and specify the StartAfter parameter.
• B. Create a batch migration and select the Automatically complete the migration batch check box.
• C. Run the New-MigrationBatch cmdlet and specify the CompleteAfter parameter.
• D. Create a script that moves most of the mailboxes on Friday at 22:00 and the remaining mailboxes on Monday at 09:00.

Correct answer: A

Explanation

The correct answer is A because using the New-MigrationBatch cmdlet with the StartAfter parameter allows you to schedule the migration to start during the weekend, aligning with the requirement to minimize disruption. Options B and C do not allow for scheduling the start time as needed, and D, while it suggests a staggered approach, does not utilize the built-in migration tools effectively, which could complicate the process.
