Which migration solution should you recommend for Project1?
A . From the Microsoft 365 admin center, start a data migration and click Exchange as the data service.
B . From the Exchange admin center, start a migration and select Cutover migration.
C . From the Exchange admin center, start a migration and select Staged migration.
D . From the Microsoft 365 admin center, start a data migration and click Upload PST as the data service.
Answer: A
Explanation:
Project1: During Project1, the mailboxes of 100 users in the sales department will be moved to Microsoft 365.
Fabrikam does NOT plan to implement identity federation.
All users must be able to exchange email messages successfully during Project1 by using their current email address.
During Project1, some users will have mailboxes in Microsoft 365 and some users will have mailboxes in Exchange on-premises. To enable users to be able to exchange email messages successfully during Project1 by using their current email address, we’ll need to configure hybrid Exchange.
A new way to migrate mailboxes in a hybrid Exchange configuration is to use the Microsoft 365 data migration service. The data migration service can migrate Exchange, SharePoint and OneDrive. Therefore, we need to start a data migration and click Exchange as the service to be migrated.
