Introduction

This tutorial provides a comprehensive guide on performing a Microsoft 365 Tenant to Tenant migration for free using native Office 365 tools. It is designed to help you seamlessly transition mailboxes from one tenant to another, ensuring minimal disruption to your business operations.

Step 1: Prepare the Source and Destination Tenants

• Verify Admin Access: Ensure that you have administrative access to both the source and destination Microsoft 365 tenants.
• Review Licensing: Confirm that the destination tenant has the necessary licenses to accommodate the migrated mailboxes.
• Plan the Migration: Outline which mailboxes, data, and settings need to be migrated to avoid missing critical information.

Step 2: Configure DNS Records

• Identify DNS Records: Make a list of all relevant DNS records for the source tenant, including MX, CNAME, and TXT records.
• Update DNS Settings: Prepare to update DNS records in the destination tenant once the migration is complete to ensure proper mail flow.

Step 3: Set Up the Migration Environment

• Enable Mailbox Permissions: Grant necessary permissions on both tenants to allow migration. This may include assigning admin roles or mailbox delegation.
• Use the Microsoft 365 Admin Center: Access the Admin Center in both tenants to manage settings and monitor the migration process.

Step 4: Create Migration Endpoints

• Access Exchange Admin Center: Log into the Exchange Admin Center of the destination tenant.
• Create Migration Endpoints:
  • Navigate to the "Migration" section.
  • Select "Endpoints" and choose "New" to create a new migration endpoint.
  • Enter the source tenant details including the server name and credentials.

Step 5: Initiate the Migration Batch

• Create a Migration Batch:
  • Still in the Exchange Admin Center, navigate to "Migration."
  • Select "New Migration Batch" and follow the prompts to add user mailboxes to the batch.
• Start the Migration: Once the batch is created, start the migration process. Monitor the progress in the Admin Center.

Step 6: Monitor the Migration Process

• Check Migration Status: Regularly check the status of the migration batch. Look for any errors or issues that may arise during the process.
• Resolve Issues: If there are migration failures, review the error messages and take corrective actions as needed.

Step 7: Perform Post-Migration Tasks

• Verify Data Integrity: Ensure all mailboxes have been migrated correctly and that data is intact.
• Update DNS Records: Once satisfied with the migration, update the DNS records to point to the new tenant.
• Train Users: Provide training or resources to users in the destination tenant to help them acclimate to any changes.
