Let’s suppose your company has just merged with another business. Overnight, you have hundreds of devices, all enrolled under different Microsoft Intune tenants. Each device has its own policies, apps and configurations. Now the IT department needs to unify everything into a single, secure environment without disrupting user productivity or losing compliance.

This sounds so simple but in real, it’s not.

In reality, intune tenant to tenant migration is one of the most complex tasks IT teams face. It’s not just about moving devices, it’s about maintaining data integrity, security and business continuity throughout the process.

And here, TECHOM Systems steps in; helping businesses across Australia plan, automate and execute secure Microsoft Intune migrations with minimal downtime.

Why Is Tenant To Tenant Intune Device Migration So Complicated?

why is device migration complicated

Tenant to Tenant Intune device migration may seem like a simple process. You are just moving devices from one tenant to another, right? But once you start digging deeper, the complexity becomes clear.

Behind the scenes, there are many technical layers that need to be aligned perfectly. This includes policies, security rules, access controls and more. For many IT teams, this quickly turns into a time consuming and error prone task. Let us take a closer look at what makes this migration so challenging.

Key Reasons Why It Gets Complicated:

  • Device already assigned to other tenant
    One of the most common issues occurs when a device is still linked to the old tenant. This can cause login errors, enrollment failures and sync problems.
  • Policy mismatches
    Conditional access policies, compliance settings and configuration profiles often need to be recreated from scratch. Even a small difference can cause major disruptions for users.
  • Licensing and compliance concerns
    Moving from one tenant to another may require new Microsoft licenses, which affects budgeting and compliance checks. Missing this step could create gaps in security or user access.
  • Identity federation and authentication
    Azure AD sync and SSO settings need to be reviewed. If not set up correctly, users may lose access or face reauthentication issues.
  • Endpoint security rules
    Antivirus, Defender or device restriction policies must match the new environment. Otherwise, device behavior or app access may break post migration.

These technical details show that moving devices from one tenant to another is not just about clicking a few buttons. It requires planning, testing and a solid understanding of Microsoft 365 architecture.

If you want to avoid these roadblocks and ensure smooth migration, let TECHOM Systems take care of it for you.

🧭 Did You Know:

💡 Nearly 70% of IT teams underestimate the time and technical effort required to move devices between tenants.

⚙️ Policy mismatches and device identities are the top causes of migration failure.

📦 Without proper offboarding, a device assigned to another tenant can block re-enrollment completely.

💰 Businesses that plan migrations in phases reduce downtime by over 60%.

Partnering with certified Microsoft experts like TECHOM Systems ensures better compliance and smoother execution.

Microsoft Intune Migration Steps You Should Follow

A successful Tenant to Tenant Intune device migration does not happen without a proper plan. If any step is missed, it can lead to downtime, user access problems or policy conflicts. That is why following a step by step approach is essential. Here are the most important Microsoft Intune migration steps that should be followed to ensure a smooth transition:

Step 1: Pre-Migration Planning

Before you touch any configuration, take the time to understand your current Intune environment. This stage sets the foundation for a seamless migration by identifying what needs to move, what can be rebuilt and where potential risks may exist.

  • Inventory all devices and user assignments.

  • Review policies, compliance rules and apps currently in use.

  • Identify licensing gaps, compatibility issues and non-compliant devices.

  • Document dependencies such as VPN, certificates or third-party connectors.

Step 2: Tenant Configuration

Once planning is complete, prepare the new destination tenant. This involves replicating existing Intune configurations, assigning the right licenses and ensuring the environment is ready to accept migrated devices.

  • Prepare the destination tenant and apply proper licenses.

  • Recreate Intune policies, compliance profiles,and app configurations to mirror the source tenant.

  • Align domain settings, SSO integration and authentication mechanisms.

  • Validate user roles and permissions before enrollment begins.

Step 3: Device Offboarding

This phase focuses on safely detaching devices from the source tenant without losing security or data integrity. Proper offboarding prevents enrollment conflicts and ensures clean re-registration in the new tenant.

  • Safely remove devices from the source tenant.

  • Resolve “device assigned to other tenant” errors to prevent migration blockages.

  • Remove device objects, stale certificates and residual Intune bindings from Azure AD.

  • Confirm that each device is fully unenrolled before moving to the next phase.

Step 4: Re-Enrollment

After offboarding, devices are enrolled into the new Intune tenant. This step reconnects your fleet with new management policies, ensuring configurations and compliance are applied consistently.

  • Re-enroll devices into the new tenant using Windows Autopilot, manual enrollment or PowerShell automation scripts.

  • Confirm successful device registration, compliance and policy deployment.

  • Ensure endpoint protection, encryption and application policies are correctly applied.

  • Automate user reassignment and device tagging where possible.

Step 5: Validation and Testing

Once migration is complete, it’s time to validate and fine-tune. Testing ensures every device operates as intended, all applications deploy successfully and users can access resources without interruption.

  • Validate compliance posture, app delivery and security baselines.

  • Test connectivity and access to Microsoft 365, Teams and SharePoint.

  • Confirm that conditional access and MFA policies function correctly.

  • Remediate any non-compliant or failed devices before final handover.

Best Practices For Intune Tenant Migration

practices for Microsoft Intune

Every business wants a smooth and secure migration. But without the right strategy, even a small mistake can lead to login issues, lost data or downtime. That is why following proven steps is so important during a Tenant to Tenant Intune device migration.

Over time, the experts at TECHOM Systems have developed these best practices while working on successful projects across Australia. These tips can help your business avoid common problems and stay compliant throughout the process.

Key Best Practices For Intune Tenant Migration:

  • Start with a pilot rollout
    Always begin by migrating a small batch of 5 to 10 devices. This helps you identify potential issues before they affect your entire environment, making the full rollout more predictable and safer.
  • Back up all important configurations
    Use PowerShell scripts or export tools to save policies, configuration profiles and app settings. Having a backup gives you peace of mind and allows for faster recovery if anything goes wrong.
  • Check license compatibility
    Before migrating, verify that both the source and destination tenants have proper Microsoft 365 and Intune licenses. Mismatched plans can lead to device blocking, enrollment failures or feature limitations.
  • Communicate with users early
    Let your employees know what changes are coming, when to expect them and how it may affect their work. Clear communication helps reduce confusion and lowers the number of support requests during migration.
  • Match conditional access policies
    Review and align your security settings and access rules in both tenants. This helps maintain a secure environment and prevents login issues after re enrollment.

Following these best practices for Intune tenant migration helps you avoid disruption and ensures everything runs smoothly from start to finish.
