SPMT vs Migration Manager: Which Microsoft Tool Should You Use?
SPMT vs Migration Manager: Which Microsoft Tool Should You Use for SharePoint and File Shares?
Start with our full breakdown in SharePoint Migration Tools: How to Choose the Right Stack (2026), featuring a complete comparison table, evaluation criteria, and scenario-based recommendations to help you design the right migration approach from day one
What Each Tool Is Designed to Do
SPMT (SharePoint Migration Tool) is Microsoft's free command-line migration tool for moving content from supported on-premises sources into Microsoft 365. It migrates content from SharePoint Server (2010, 2013, 2016, 2019), SharePoint Foundation (2010, 2013), and local and network file shares into SharePoint Online, OneDrive, and Teams. SPMT 4.0 and later includes an integrated SharePoint Server assessment that scans source sites, shows a dashboard with content inventory and migration risks, and provides downloadable reports.
Migration Manager is Microsoft's modern migration management experience, available through the Microsoft 365 admin centre and SharePoint admin centre. It supports migrations from file shares, Google Workspace, Box, Dropbox, Egnyte, and SharePoint Server into Microsoft 365. For file share migrations, Migration Manager uses lightweight agents installed on computers or virtual machines, with tasks created centrally and automatically assigned to available agents.
Best-Fit Scenarios
SharePoint Server migrations
SPMT is the primary Microsoft tool for SharePoint Server-to-SharePoint Online migrations. It supports permissions, versions, metadata, taxonomy, pages, incremental migration, and PowerShell for scripted or repeatable tasks. SPMT 4.0 scan provides a pre-migration assessment for SharePoint Server sources.
File shares at scale (agents and task management)
Migration Manager is usually the better choice for larger file-share projects because it provides centralized task management, agent-based scaling across multiple machines, scanning, reporting, and support for file-share migrations to SharePoint, OneDrive, and Teams. SPMT remains useful for smaller or more direct file share migrations, especially when the team is comfortable running a local tool without the agent-management model.
Cloud sources: Google Workspace, Box, Dropbox, Egnyte
Migration Manager is Microsoft's path for migrating data from supported cloud storage platforms. Google Workspace, Box, Dropbox, and Egnyte migrations are integrated into Migration Manager after the retirement of Mover.io for admin-led migrations. SPMT does not support these cloud sources.
Migration Manager does not support migrations to Amazon S3 or Azure Blob Storage.

| Incremental migration | Yes | Yes |
| Permissions migration | Yes (requires planning) | Yes (requires identity mapping) |
| Metadata and versions | Yes | Yes |
| PowerShell support | Yes | Limited (admin centre focus) |
| Central task management | No (local tool) | Yes |

| Licensing | Free | Free |
Common Gotchas and Planning Tips
Permission migration requires careful planning with both tools. For SPMT, authentication scenarios can be complex in some on-premises configurations, especially when multiple authentication methods are used, including Windows authentication. For Migration Manager, identity mapping is required when preserving source permissions and metadata from cloud platforms.
Agent-based file share migrations with Migration Manager require planning for endpoint access, source permissions, network capacity, and agent placement. Start with a small batch of tasks to validate the agent configuration before scaling.
Neither tool is a substitute for content strategy, governance design, or business-led disposition. Both tools move content effectively, but they do not decide what content deserves to move.
When to Add Third-Party Tools
If the project involves tenant-to-tenant SharePoint content migration, complex SharePoint Online reorganization, detailed restructuring with validation, permission-heavy environments requiring remodelling, or large legacy SharePoint farms with publishing sites and deep customizations, native tools may not be enough on their own. ShareGate is the most common mid-market addition. Quest Content Matrix is the enterprise option for complex legacy environments.
