As part of a Microsoft 365 or Office 365 deployment, you can migrate the contents of user mailboxes from a source email system to Microsoft 365 or Office 365. When you do this all at one time, it's called a cutover migration. Additionally, this migration method moves mail users, mail contacts, and mail-enabled groups with their membership. 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.
If a cutover migration won't work for you, see Ways to migrate email to Microsoft 365 or Office 365 for other options.
Setting up an email cutover migration to Microsoft 365 or Office 365 requires careful planning. Before you begin, here are a few things to consider:
•You can move your entire email organization to Microsoft 365 or Office 365 over a few days and manage user accounts in Microsoft 365 or Office 365.
•A maximum of 2,000 mailboxes can be migrated to Microsoft 365 or Office 365 by using a cutover Exchange migration. However, it is recommended that you only migrate 150 mailboxes.
•The primary domain name used for your on-premises Exchange organization must be an accepted as a domain owned by you in your Microsoft 365 or Office 365 organization.
After your on-premises and Microsoft 365 or Office 365 organizations are set up for a cutover migration, post-setup tasks could impact your users.
•Administrators or users must configure desktop computers: Make sure that desktop computers are updated and set up for use with Microsoft 365 or Office 365. These actions allow users to use local user credentials to sign in to Microsoft 365 or Office 365 from desktop applications. Users with permission to install applications can update and set up their own desktops. Or updates can be installed for them. After updates are made, users can send email from Outlook 2013, Outlook 2010, or Outlook 2007.
The main steps you perform for a cutover migration are shown in the following illustration.
1.The administrator communicates upcoming changes to users and verifies domain ownership with the domain registrar.
2.The administrator prepares the servers for a cutover migration and creates empty mail-enabled security groups in Microsoft 365 or Office 365.
3.The administrator connects Microsoft 365 or Office 365 to the on-premises email system (this is called creating a migration endpoint).
4.The administrator migrates the mailboxes and then verifies the migration.
5.Grant Microsoft 365 or Office 365 licenses to your users.
If you're comfortable setting up a migration to Microsoft 365 or Office 365, here are the tasks that need to be done:
•Set up Exchange Server by using the Exchange admin center.
•Change your organization's MX record to point to Microsoft 365 or Office 365 when the migration is complete. Your MX record is how other mail systems find the location of your email system. Changing your MX record allows other mail systems to begin to send email directly to the new mailboxes in Microsoft 365 or Office 365. We provide instructions on how to do this for many DNS providers. To set up your public DNS servers, you need to change your organization's MX record to point to Microsoft 365 or Office 365 if you choose to route all incoming internet mail for your on-premises Exchange organization through Microsoft 365 or Office 365.
