18 Jun Cross-Tenant SharePoint Migration: A Complete Guide for Enterprise IT
Introduction:
Cross-tenant SharePoint migration refers to the process of transferring SharePoint Online sites, documents, libraries, and related assets from one Microsoft 365 tenant to another.
This is a common need during mergers, acquisitions, divestitures, or IT reorganizations. As cloud adoption grows and businesses restructure digitally, enterprise IT leaders are increasingly faced with the challenge to migrate SharePoint sites to another tenant—without downtime, data loss, or compliance risks.
In this blog, we’ll break down everything you need to know about tenant-to-tenant SharePoint migration, including use cases, benefits, and how to choose a provider that ensures success.
What Is Cross-Tenant SharePoint Migration?
Cross-tenant SharePoint migration involves moving content, permissions, metadata, and user access from one Microsoft 365 tenant’s SharePoint environment to another.
Common Assets Migrated:
- Document libraries and folders
- Lists and list items
- SharePoint pages and web parts
- Workflows and permissions
- Site collections, subsites, and hub associations
This process is technically complex due to the limitations of Microsoft’s native tools, differences in tenant configurations, and identity mapping requirements.

- Streamlined Post-Merger Integration (PMI)

- Improved Compliance and Governance
Ensure that records management, DLP policies, and access controls are consistently applied across the new tenant, reducing regulatory risk.
- Enhanced User Experience
A centralized SharePoint environment means fewer login credentials, seamless access to data, and reduced IT support tickets.

Migrating SharePoint Online to SharePoint Online between tenants allows for scalable and modern digital workplace experiences that align with Microsoft 365 best practices.
