Your company has an on-premises Microsoft Exchange Server 2016 organization. The organization is in the company’s main office in Melbourne. The main office has a low-bandwidth connection to the Internet.
The organization contains 250 mailboxes.
You purchase a Microsoft 365 subscription and plan to migrate to Exchange Online next month.
In 12 months, you plan to increase the bandwidth available for the Internet connection.
You need to recommend the best migration strategy for the organization. The solution must minimize administrative effort.
What is the best recommendation to achieve the goal? More than one answer choice may achieve the goal. Select the BEST answer.
A . network upload
B . cutover migration
C . hybrid migration
D . staged migration
Answer: C
Explanation:
With a hybrid migration, you can migrate the mailboxes in small batches over a period of time which will help to avoid saturating the bandwidth. With the migration wizard, you can configure a migration batch to start outside office hours which would minimize bandwidth usage during office hours.
With a hybrid migration, you do not need to reconfigure Outlook to connect to the migrated mailbox.
Outlook will automatically detect the new mailbox location. This reduces administrative effort.
Incorrect Answers:
A: ‘Network upload’ is not a defined migration strategy.
B: With a cutover migration, all mailboxes are migrated in one go. This is not suitable for a low bandwidth Internet connection. You would also need to manually reconfigure Outlook for each user which does not meet the requirement of minimizing administrative effort.
D: With a staged migration, mailboxes are migrated in batches. However, Microsoft recommends using a
staged migration when you have more than 2000 mailboxes. You would also need to manually reconfigure Outlook for each user which does not meet the requirement of minimizing administrative effort.
