Graph API Integrated Migration

The technology foundation behind Microsoft 365 workload migration

Large-scale Microsoft 365 migrations often require more flexibility than native migration options provide. The Microsoft 365 Tenant Migration Tool leverages the Microsoft Graph API to securely access mailboxes, SharePoint sites, OneDrive accounts, and related workloads. It supports modern authentication, incremental migration, metadata preservation, and structured data transfer, helping organizations manage tenant migrations efficiently across source and destination environments.

Why Use Graph API for Microsoft 365 Migration?

  • Official Microsoft 365 integration framework.
  • Supports OAuth 2.0 and MFA authentication.
  • Unified access to Exchange, SharePoint, and OneDrive.
  • Enables incremental and large-scale migrations.
  • Preserves metadata and folder hierarchy.
  • Built for enterprise-scale Microsoft 365 environments.

Graph API vs General Cloud Platforms

Azure, AWS, and Google Cloud Platform provide cloud infrastructure, storage, networking, and computing services. Microsoft Graph API serves a different purpose by providing programmatic access to Microsoft 365 data and services. For Microsoft 365 tenant migration, Graph API enables direct interaction with tenant resources, making it the preferred integration layer for mailbox, SharePoint, and OneDrive migration workflows.

What Are the Microsoft Graph API Migration Boundaries?

  • Public and shared mailboxes can be migrated, while group and archive mailboxes are not supported.
  • OneDrive migration does not support malicious or infected files.
  • SharePoint migration supports only generic content and does not include custom configurations, workflows, permissions, or archive version history.
