Migrate OneDrive From One Tenant to Another Without Data Loss (2026 Guide)

What Is Cross-Tenant OneDrive Migration?

Cross-tenant OneDrive migration is basically moving a user’s OneDrive content, files, folders, version history, permissions, all of it, from one Microsoft 365 tenant to another. You’ll usually see this come up during mergers, acquisitions, or when a business unit splits off on its own. It’s not the same as a regular backup. This kind of move has to keep metadata intact. Sharing links need to keep working. And the folder hierarchy has to stay structurally consistent too. Otherwise, employees land in the new tenant and can’t find anything or, worse, can’t get back to work at all.

Why do organizations migrate OneDrive data between Tenants?

• Mergers & Acquisitions – Consolidate users and data into a single Microsoft 365 tenant.
• Tenant Consolidation – Simplify IT management by reducing multiple tenants.
• Business Separation – Move OneDrive data when a business unit is spun off.
• Domain Change or Rebranding – Align user data with a new Microsoft 365 tenant and domain.
• Security & Compliance – Implement stronger security policies and centralized governance while preserving business data.

Prerequisites for Cross-Tenant OneDrive Migration

• Verify Both Microsoft 365 Tenants – Make sure the source and destination tenants are active and set up right.
• Assign Required Licenses – Get the Cross-Tenant User Data Migration licenses for the users who need them.
• Configure Microsoft Entra Cross-Tenant Access – Set up trust between the source and destination tenants.
• Create User Mapping – Match each source account to its destination account, usually with a CSV file.
• Grant Required Permissions – Global admins need the right permissions before the migration can even start.
• Provision OneDrive Accounts – Make sure OneDrive for Business is already up and running for destination users.
• Verify Storage Availability – Check the destination tenant actually has room for all that data.
• Notify End Users – Give people a heads up about the schedule and any downtime they should expect.

Methods to Migrate OneDrive from One Tenant to Another

Admins can move OneDrive data between tenants using either Microsoft’s native method or a dedicated migration tool. Which one makes sense really comes down to how many users you’re dealing with and how much automation you actually need.

Method 01: Native Method to Move OneDrive from One Tenant to Another

OneDrive data can also be transferred using Microsoft’s native migration option. This method depends on SharePoint Online PowerShell and involves several manual setup steps.

Step 01: Verify the Prerequisites

First, complete the required preparation before starting the migration.

1. Sign in to both the source and destination Microsoft 365 admin centers.
2. Verify that both tenants are active and supported for cross-tenant migration.
3. Assign the required Cross-Tenant User Data Migration licenses.
4. Finally, install the latest SharePoint Online Management Shell on your system.

Step 2: Connect to Both Tenants

Next, connect to the source and destination Microsoft 365 tenants.

1. Open the SharePoint Online Management Shell as an administrator.
2. Connect to the source tenant using SharePoint Online PowerShell.
3. Then, connect to the destination tenant with administrator credentials.
4. Lastly, verify that both tenant connections are successful before continuing.

Step 3: Configure Cross-Tenant Trust

After that, establish a trust relationship between the two tenants.

1. Open the Microsoft 365 Admin Center.
2. Then, configure Cross-Tenant Access Settings in Microsoft Entra ID.
3. Next, add the destination tenant to the trust relationship.
4. Grant the required permissions for cross-tenant migration.
5. Finally, save the configuration and verify that the trust has been established successfully.

What Are the Loopholes of the Native Method?

• You need PowerShell knowledge to complete the migration.
• The setup takes time because several configurations are required.
• Most tasks require manual work with very little automation.
• You need additional Microsoft migration licenses before the process can begin.
• Large user migrations increase the chance of errors and require more effort.
