Data Migration

FastTrack can help you migrate mail and file data in your source environments to Office 365 (Exchange Online, SharePoint Online, and OneDrive for Business).

The type of assistance we provide depends on your number of Office 365 licenses:

  • For Office 365 tenants with 150-499 licenses: FastTrack provides migration guidance only; you are responsible for performing the data migration. We guide you through documentation that helps you plan and use free tools to perform a self-service migration.
  • For Office 365 tenants with 500 or more licenses: FastTrack provides migration guidance and data migration services. We provide guidance to help you plan your migration, configure your source environments and Office 365 tenant, and leverage our data migration services to migrate your data. You create and schedule your migration events. We launch migration events in accordance with your schedule, monitor their progress, and provide status reports.

Note

If you purchased or renewed a commercial plan prior to 9/1/2017, you need only 150 licenses to qualify for data migration services. For education plans, only your paid faculty and staff licenses are eligible for data migration services.

Considerations

  • Your source environments must meet specific expectations in order to migrate data to Office 365. Refer to Products and Capabilities for more information on the source environment expectations for Exchange, SharePoint, and OneDrive for Business.
  • We require appropriate access and permissions to your source environments and Office 365 tenant to provide data migration services.
  • Our data migration services are neither designed nor intended for data subject to special legal or regulatory requirements. As we migrate your data, it can be transferred to, stored, and processed anywhere that we maintain facilities (except as otherwise provided for your FastTrack migration project).
  • We can’t guarantee the speed of mail or file migrations.
  • Unforeseen issues (like unreadable or corrupt items in the source environment) may prevent our ability to migrate of some of your data items.
  • External factors beyond our control (like changes to third-party application programming interfaces (APIs)) can result in changes to, delays in, or suspension of our data migration services.

Migration service availability

  • For Commercial and UK Government customers: We provide data migration services 24 hours a day, seven (7) days a week (24x7).
  • For US Government/DOD customers: We provide data migration services 24 hours a day, five (5) business days a week (24x5).

Migration to Exchange Online

When you choose to use FastTrack to migrate your email to Exchange Online, we provide migration guidance and data migration services. We provide guidance to help you plan your migration, configure your source environments and Exchange Online, and leverage our data migration services to migrate your mailboxes. You create and schedule your migration events. We launch migration events in accordance with your schedule, monitor their progress, and provide status reports. When your migration events complete, you can expect mail from appropriately scheduled and eligible source mailboxes of your source environments to have been migrated to Exchange Online.

Considerations

  • Prior to migration, you must complete FastTrack core onboarding for Exchange Online;
    • If you performed onboarding yourself, you must pass the required checks and prerequisites. Refer to Products and Capabilities for details.
  • FastTrack migrates only to active Office 365 mailboxes.
  • You must satisfy specific requirements if you intend to migrate from an on-premises Exchange environment. Refer to Hybrid deployment prerequisites for details.
  • Each source environment must be on the latest service pack (SP) and rollup (RU)/cumulative update (CU) level for the respective product in the source environment.
  • Distribution lists (MailEnabledGroup objects) and external contacts (MailEnabledContact objects) that exist in your on-premises Active Directory aren’t a part of mailbox data migration. However, you can synchronize them using Azure Active Directory (Azure AD) Connect.

Source environments

Our data migration service migrates data from these source environments:

  • A single or multiple Active Directory forests with single or multiple Exchange organizations (each Exchange mail system must be Exchange 2010 or greater).
  • A single IMAP-capable email environment.
  • G Suite environment (Gmail, Contacts, and Calendar only).

The following table presents migration details specific to each source environment:

Source environment Type of migration What migrates What doesn’t migrate
Exchange 2010, Exchange 2013, Exchange 2016, Exchange 2019
