Comparing Microsoft 365 tenant-to-tenant migration tools

Tenant‑to‑tenant migrations are no longer rare projects for IT admins. They're a standard part of how organizations evolve through mergers, divestitures, acquisitions, rebranding and other business changes.

These Microsoft migrations usually involve many complex technical considerations and details to get right. Your content likely lives across Exchange Online, SharePoint Online, OneDrive for Business, Microsoft Teams, and each tenant’s workload brings its own rules for structure, permissions, and metadata.

While keeping everything intact during the move is challenging, the right migration tool makes the process less overwhelming. This article walks you through the most common tools for migrating between tenants. You'll also see how the native Microsoft options compare with third‑party solutions like ShareGate Migrate for your migration project’s size, complexity, and timeline.

Understanding the complexities of Microsoft 365 tenant-to-tenant migrations 

Ask any IT admin who’s been through a tenant‑to‑tenant migration during mergers and acquisitions or other scenarios, and they’ll tell you the real work begins long before the migration itself.

With data to migrate across multiple Microsoft 365 workloads and fragmented visibility across the tenant, it’s hard to keep everything consistent when merging or migrating between tenants or cross-tenant.

Unfortunately, you can’t just hit a button to trigger a straightforward lift-and-shift to your destination tenant. For a successful migration, admins must coordinate a sequence of workload‑specific moves across Microsoft services like Exchange Online, SharePoint Online, OneDrive for Business, and Teams. And each has its own limits, dependencies, and rules for handling and transferring content.

Before you can migrate to your destination, you need to clearly understand the current tenant:

•  What content exists

•  Where it lives

•  How it’s structured

•  Who has access

•  How workloads relate to each other

Gaining that visibility is often the hardest part. Auditing your environment manually takes time, especially with a large or long-standing tenant. During the migration process, you’ll likely risk missing, duplicating, or misconfiguring content as you transfer data. Once the migration begins, it’s also harder to verify your destination tenant is accurate and complete.

Yet with an enterprise-grade, automation‑enabled migration tool to run your Microsoft migration, your team can reduce manual work and prevent any scoping surprises. You also access comprehensive reporting to confirm that all your data, structure, and permissions made it to the destination tenant as expected.

Comparing the best Microsoft 365 tenant-to-tenant migration tools

You’ve seen how tools can streamline your Microsoft 365 tenant‑to‑tenant migration. Now it’s time to pick the best one for your migration project. You have two main paths available: Microsoft’s native options or a third‑party solution. The right fit will depend on what needs to move, your tenant’s complexity, and how much control or automation you want as you transfer data.

​For a smaller, straightforward move, native tools will likely work just fine. But when undergoing a big project like a rebranding or merger, most IT admins prefer a third-party solution's flexibility and visibility for multi-workload, time-sensitive, or complex Microsoft projects. Let's see how each top migration tool supports (or doesn’t support) the full migration lifecycle, from early assessment and planning through execution, validation, and reporting.

ShareGate Migrate

Tenant‑to‑tenant migrations move faster when you can know the full context and take action without the extra steps. ShareGate Migrate gives you that control. The platform supports migration planning, execution, and validation across all workloads, including SharePoint, OneDrive for Business, Teams, Exchange Online, and Google Workspace, while the overall migration process stays manageable for your team.

You get clear visibility into both your source and destination tenants, so you can scope the work, understand any complexities, and confirm that everything lands correctly after you migrate.

Once the migration starts, automapping capabilities help you speed up transferring your permissions, metadata, and Microsoft Purview sensitivity labels, while preserving everything in your destination tenant.

Reporting is also available throughout the migration project:

• Pre‑migration planning to understand what’s in scope
  
  
• In‑progress monitoring to keep things on track during the transition
  
  
• Post‑migration validation to confirm that you've successfully transferred everything to your destination tenant
  
  

Importantly, ShareGate Migrate is offered with straightforward pricing that doesn’t limit how much data you can move or which supported workloads you can migrate. Plans include multiple machine activations so teams can run migrations concurrently across workstations, and everything happens from a single interface without switching between different tools.

Microsoft native tools

One thing becomes clear quickly when using Microsoft’s native options for tenant‑to‑tenant migration: nothing lives in one place. Migration capabilities are spread across different Microsoft 365 services, requiring two separate licensing add‑ons:

1) Cross‑Tenant User Data Migration: Licensed per user and helps you migrate user‑associated data in Exchange Online and OneDrive for Business.

2) Cross‑Tenant Shared Data Migration: Licensed per 100GB of data moved, limited to Enterprise Agreement customers, and supports moving shared content stored in SharePoint Online sites.

These native capabilities require workload-specific setup: Exchange Online PowerShell scripts for mailbox moves and SharePoint Online PowerShell for OneDrive and SharePoint moves.

And while there’s no full dedicated Teams‑to‑Teams migration tool, you can still migrate some Teams content to your new target. You can migrate the SharePoint site content behind Teams (files stored in the connected SharePoint site) using Cross-Tenant Shared Data Migration, but that doesn’t migrate the Team/channel structure itself.  In preview, Microsoft’s tenant-to-tenant migration with orchestrator supports migrating Teams chats and meetings—and Teams meetings depend on a successful mailbox migration.

All of these native Microsoft capabilities can help you tackle certain parts of your tenant‑to‑tenant move. But you still don’t get a complete, end‑to‑end migration solution that carries you through planning, execution, and validation.

BitTitan MigrationWiz 

MigrationWiz is a common option for handling tenant‑to‑tenant migrations.

It supports several Microsoft 365 workloads, including migrating content from Exchange Online, OneDrive for Business, SharePoint Online, and Microsoft Teams and Planner. For mailbox-focused migration, MigrationWiz handles a range of migration scenarios, including moving mailboxes from various source environments to a Microsoft 365 tenant.

MigrationWiz can also migrate Teams channels, files, conversations, Planner plans/tasks/buckets/tabs, and much of the related metadata, though some advanced metadata or large task counts may have specific limitations.

When it comes to reporting, MigrationWiz focuses primarily on migration progress and status. For deeper pre-migration assessment and post-migration validation typically, you’ll need additional planning or separate tools, rather than having those capabilities built directly into the MigrationWiz reporting experience.

Ultimately, MigrationWiz can be a good fit for migrating specific Microsoft 365 workloads when the scope is well defined, but larger tenant-to-tenant projects may require broader assessment, coordination, and validation beyond what MigrationWiz provides out of the box.

Quest On Demand Migration

For certain projects that need a more structured, enterprise‑level migration, some admins will choose Quest On Demand Migration. This tool covers various Microsoft 365 workloads, including Exchange Online, OneDrive for Business, SharePoint Online, Microsoft Teams, and Planner. (Note: Planner elements are included in the Teams migration flow rather than handled separately.)

You also get built-in discovery, pre‑migration assessment, and centralized dashboard reporting, which can help you understand what’s in scope and how the migration is progressing. 

However, there’s a tradeoff. This level of depth usually takes more setup and planning, which can add complexity to the migration process . ODM fits best for larger or highly regulated tenants in organizations where teams have dedicated migration resources or partner support.

Ensuring a smooth tenant-to-tenant migration and ongoing tenant health

Microsoft 365 environments rarely stay still in the real world. As organizations face mergers, divestitures, acquisitions, rebranding, and other changes, their digital footprint shifts, too. These changes often mean reshaping things and supporting new ways of working by moving and merging data between tenants. And so, IT teams find themselves returning repeatedly to tenant‑to‑tenant migrations.

When migration is an ongoing operational responsibility, you can turn to ShareGate Migrate. With advanced assessment, planning, execution, and validation capabilities, your team gets a dependable way to handle each stage of the migration process and rely on controlled, repeatable execution.
