Exam MS-100 topic 7 question 3 discussion

-From The Exchange admin center, start Migration and select staged migration

Ill go with this answer

Would go towards A but it's really hard to make a decision here. https://learn.microsoft.com/en-us/exchange/mailbox-migration/decide-on-a-migration-path 'Fewer than 150 Slowly, by migrating a few users at a time. Exchange Hybrid'

Exchange as Data Service is the correct answer as the On-premises Exchange is exchange 2016. https://www.nucleustechnologies.com/blog/exchange-server-2016-hybrid-migration-to-office-365/

Export and import PST is the correct solution in this scenario.

I dont think cutover will sove the problem. Becouse we are only migrateing 1 Department and the otherones nees to stay onprem

A. From the Microsoft 365 admin center, start a data migration and click Exchange as the data service. Yes, then apply option B B. From the Exchange admin center, start a migration and select Cutover migration. Yes, Choosing a cutover migration is suggested when: Your current on-premises Exchange organization is Microsoft Exchange Server 2003 or later. Your on-premises Exchange organization has fewer than 2,000 mailboxes C. From the Exchange admin center, start a migration and select Staged migration. No,A staged migration is recommended when: Your source email system is Microsoft Exchange Server 2003 or Microsoft Exchange Server 2007, or you have more than 2,000 mailboxes D. From the Microsoft 365 ad

In the EAC, go to Office 365 > Recipients > Migration. Click Add Add Icon., and then select Migrate to Exchange Online. On the Select a migration type page, select Remote move migration and then click Next. On the Select the users page, click Add Add Icon. and select the on-premises users to move to Microsoft 365 or Office 365 and click Add and then click OK. Click Next.

So Remote Move ist the way to go but I dont find this: From the Microsoft 365 admin center, start a data migration and click Exchange as the data service.

From the Microsoft 365 admin center, start a data migration and click Exchange as the data service - This doesnt exists! Microsoft 365 Admin Centre > Setup > Migrations > Email> Get Started > Import my PST files - this should be the Answer

I misread the question: It's not selecting the Cutover answer but Remote Move (as indicated by picking a migration source -- that's part of a remote move because you have to indicate whether you're going from cloud to on-prem or on-prem to cloud). That's a good choice and you can select the users to migrate using a remote move. Staged migration is only available on 2007 and 2010. My bad.

The discussion in the "Show Solution" is great but the provided answer (Cutover) is wrong. You should use Cutover only when moving all the mailboxes (up to 2000 but 150 is the recommended target): https://docs.microsoft.com/en-us/exchange/mailbox-migration/cutover-migration-to-office-365. If you're moving some (not all) of your mailboxes, which is what this question asks, you want to do a staged migration by providing a list of users to migrate in a CSV file: https://docs.microsoft.com/en-us/exchange/mailbox-migration/perform-a-staged-migration/perform-a-staged-migration
