Planning Microsoft 365 Tenant to Tenant Migration
A successful Microsoft 365 tenant to tenant migration starts with planning. Enterprises that take time to analyze, scope and prepare are more likely to have a smooth and disruption-free migration. Here are the key steps to include in your planning phase:
1. Pre-Migration Assessment
Start by performing a thorough evaluation of your source Microsoft 365 tenant. This includes analyzing user accounts, mailboxes, SharePoint sites, OneDrive data, Microsoft Teams channels, licenses and security settings. By knowing what to migrate and what to archive, your IT team can prepare a precise migration scope.
2. Define the Scope of Work
Not everything needs to be moved. For example, legacy content, inactive accounts or unused SharePoint sites may not add value to the new tenant. Clearly define which users, files, emails and Teams data must be migrated. Reducing the migration scope can shorten timelines, save costs and reduce risk for enterprises with massive data.
3. Choosing the Best Office 365 Tenant To-Tenant Migration Tool
Choosing the right tool is key to your project’s success. Look for:
- Fast data transfer at scale
- Accurate user mapping across tenants
- Full-fidelity Teams migration (channels, chats, files, permissions, apps)
- Delta migration for incremental updates
- Enterprise-grade security with compliance certifications (ISO 27001, SOC 2 Type II, GDPR)

Microsoft 365 Tenant to Tenant Migration Steps
It is always best to perform Microsoft Office 365 tenant to tenant migrations of any scale with a phased approach to migrate OneDrive, SharePoint Online, Microsoft Teams, Exchange, and others, one at a time.
Migrating from one Office 365 tenant to another is a multi-faceted undertaking. However, we have listed an overview of the migration processes below.
Contact our migration team to request an assisted trial where you can watch our migration platform in action. Or request a POC to get insights into the tool’s capabilities to cater to your company’s highly specific and granular Microsoft 365 tenant-to-tenant migration needs.
Step 1: Sign in to CloudFuze Account
The First step to migrate from one tenant to another in Office 365 is to create and log in to the CloudFuze account.
Step 2: Add Both the Microsoft 365 Accounts to CloudFuze
Locate the OneDrive/SharePoint icon under the list of business clouds and click on it. Log in using your Microsoft admin login credentials and authorize it. Repeat the same process to add the destination tenant.
Step 3: Add Apps From the Source and Destination Tenants
The first step is to add the apps that your organization plans to migrate. For example, from the list of apps to migrate, you may first choose to transfer users and data from the source OneDrive tenant to the destination OneDrive tenant.
Step 4: Configure the Source and Destination Tenant Apps
The next step is to visit the Team Migration section and configure the source and destination tenant apps (e.g., OneDrive for Business) in the correct order as per their domains. This process helps ensure that your IT team transfer users and data from the actual source tenant app to the destination tenant app and not the other way around.
Step 5: Map the User Accounts
In the Mapping section, map the user accounts to transfer the data in the correct path. Since user accounts in the source tenant app and destination tenant app do not match, auto-mapping does not work.
Therefore, it is a must to use the CSV mapping method. Our managed migration team can assist your IT team in creating CSV mapping for a high volume of user accounts.
Step 6: Map Permissions
Map permissions to the right users in the destination tenant. By default, the permissions are mapped with respect to the email addresses and can be customized based on the business requirements by clicking on the edit option.
Step 7: Configure Migration Options
Configure a few migration options as the final steps prior to starting the Office 365 tenant to tenant migration process. Choose the migration type as one-time for the first migration run and add all stakeholders of the project for migration report updates.
Step 8: Preview and Start the Migration
Reviewing all the selected parameters is critical to avoid any unnecessary add-ons. Once everything looks good, start the actual migration process.
Step 9: Microsoft 365 Tenant to Tenant Migration Status
After initiating the migration, you will be redirected to the Reports dashboard. The “In Progress” status indicates that the migration is currently in process.
The status turns “Processed” once the migration is completed successfully.
Post-Migration Activities
You’ve migrated the tenant. Now make sure data, permissions, and integrations work in the new environment. Here’s what your enterprise IT team should focus on:
1. Delta Migration
Perform a delta migration to capture any changes made in the source tenant during the migration process. This step makes sure that the destination tenant has the latest files, emails, and collaboration data.
2. Permissions and Access Verification
Verify all user roles, access controls and sharing permissions are correct in the destination tenant. Recheck file ownership and external sharing links to maintain business continuity and prevent unauthorized access.
3. Application and Integration Testing
Reconnect and test all third-party applications and connectors. This step ensures platforms like Microsoft Teams, SharePoint, and Outlook are connected to the enterprise ecosystem.
4. End-User Validation
Get key stakeholders and department heads to review migrated data and confirm accuracy. This will help identify any minor issues early and ensure all important workloads are up and running.
5. User Training and Communication
Give employees new credentials, folder paths, and collaboration guidelines for the new tenant. Share quick reference guides or video tutorials to get users up to speed faster and back to work with no disruption.
6. Post-Migration Optimization
Once data is verified, IT teams can adjust settings like unified security policies, retention labels, and compliance configurations to match enterprise governance standards.
7. Monitoring and Reporting
Use CloudFuze’s reporting dashboard to track migration performance and verify post-migration success metrics. This visibility will help with compliance, monitoring, and smooth operations after the migration is complete.
Cost and Time
The cost and time for a Microsoft 365 tenant-to-tenant migration depends on the amount of data, number of users and complexity of workloads (emails, OneDrive, Teams and SharePoint). At CloudFuze, we automate the process to ensure predictable timelines and costs. Our migration experts help reduce manual work, downtime, and get you to ROI faster.

Microsoft 365 Tenant to Tenant Migration Best Practices
Follow these best practices for a smooth and secure tenant-to-tenant migration with no downtime:
- Plan Well: Define what you’re migrating, such as users, mailboxes, OneDrive files, Teams data, SharePoint sites, and timelines and priorities.
- Communicate to Users: Let employees know about downtime, new login details and expected changes so they don’t get confused.
- Use Automation: Manual migrations are error-prone and downtime-causing. Use a dedicated Office 365 tenant to-tenant migration tool for accuracy and speed.
- Test with Pilot Batches: Perform a pilot migration with a small group to validate data transfer, permissions and performance before migrating all users.
- Security and Compliance First: Ensure multi-factor authentication (MFA), role-based access and regulatory compliance during and after the migration.
- Monitor and Verify: After migration, verify data integrity with reports and check that users can access all files, emails and Teams messages.
- Run Delta Migrations: Perform incremental syncs to capture changes made during the migration so nothing gets lost.
