Your company is planning to migrate to Microsoft Exchange Online. The company employs 1,000 people, each
with a mailbox currently located on Exchange 2010 on-premises. You estimate that it will take a minimum of
four weeks to migrate all mailboxes from on-premises Exchange to Exchange Online.
The company has the following migration requirements:
During the migration, do not change the existing Microsoft Outlook profiles and .ost files used by the
employees.
Ensure that email messages sent between on-premises mailboxes and online mailboxes during the
migration are secure.
Do not send email messages between on-premises mailboxes and online mailboxes over the Internet in
plain text.
You need to select the migration strategy that meets the requirements.
Which migration strategy should you use?
A.
Cutover migration only
B.
IMAP migration only
C.
Remote move migration only
D.
Staged migration only
Explanation:
In this question, we are migrating the mailboxes over a period of time (minimum of four weeks). During the
migration period, we will have a hybrid deployment where the Exchange environment exists both on-premise
and online.
To meet the requirements of the question, we can use a remote move migration.
A remote move migration is used to migrate on-premises Exchange mailboxes to Exchange Online in an
Exchange hybrid deployment. You must have an Exchange hybrid deployment to use a remote move migration.
With a hybrid deployment, you get the following capabilities:
Even if you plan to permanently move your on-premises email organization to Exchange Online and Office 365
over a longer period of time, you can take advantage of these hybrid deployment features during the transition.
Incorrect Answers:
A: A cutover migration option is for customers who want to migrate their whole environment at one time.
B: IMAP migration is targeted at customers who may be using non-Exchange-based mail systems in their
current hosted environment or have access to the data only by using the IMAP 4 protocol.
D: You can’t use a staged migration to migrate Exchange 2013 or Exchange 2010 mailboxes to Office 365.
