📱 Post-Migration Activities for Mobile Device Transition from SCCM to Intune

 Migrating mobile devices from System Center Configuration Manager (SCCM) to Microsoft Intune is a significant step toward modern endpoint management. Once the migration is complete, post-migration activities ensure the environment remains healthy, devices stay compliant, and end-users continue working without disruption.

✅ Post-Migration Checklist

Here's a comprehensive checklist of post-migration actions:

1. Validate Device Enrollment

  • Confirm that migrated devices appear in the Microsoft Endpoint Manager (MEM) portal.
  • Ensure device type and ownership (Corporate vs. Personal) are properly identified.
  • Check MDM authority is set to Intune.

2. Review Device Compliance

  • Apply or reassign compliance policies to migrated devices.
  • Check if devices are reporting compliance status correctly.
  • Remediate non-compliant devices by checking network connectivity and policy sync status.

3. Deploy Apps from Intune

  • Re-deploy critical apps (e.g., Outlook, Teams, antivirus) using Intune app deployment profiles.
  • Validate LOB apps or VPP apps (iOS) are properly deployed and functional.
  • For managed Play Store or VPP (Apple), check token expiration and sync status.

4. Security Baseline & Configuration Profiles

  • Ensure Device Configuration Profiles are assigned (Wi-Fi, VPN, Password, BitLocker, etc.).
  • Validate Security Baseline policies (e.g., Defender, Firewall, Attack Surface Reduction).
  • Migrate Conditional Access policies, if applicable.

5. Policy Conflict Resolution

  • Remove legacy SCCM policies or scripts that may conflict with Intune configuration.
  • Ensure co-management workloads are properly shifted (if co-management was used).
  • Clean up GPO remnants (if MDM Win10 was already under SCCM+GPO combo).

6. User Communication

  • Notify users about:

7. Monitoring & Reporting

  • Use Intune device reports to confirm:
  • Monitor via Log Analytics (if integrated) or Microsoft Defender for Endpoint.

8. Retire Devices from SCCM

  • Retire or remove devices from SCCM collections post-verification.
  • Decommission legacy SCCM MDM infrastructure if no longer in use.
  • Update documentation or CMDB with new Intune-based configuration.

🛡️ Precautions Before and After Migration

  • 📌 Pre-Migration
  • 🧯 Post-Migration

📊 Tools You Can Use

  • Company Portal logs for device-side troubleshooting.
  • Intune Troubleshooting Blade (MEM Admin Center).
  • Event Viewer > DeviceManagement-Enterprise-Diagnostics-Provider logs.
  • MDM Diagnostic Tool (MDMDiagReport) for Windows 10/11.

📝 Conclusion

Migrating from SCCM to Intune modernizes mobile device management but requires careful post-migration validation to ensure devices are secure, compliant, and productive. A detailed checklist, early issue identification, and proactive monitoring are key to a successful transition.

4 Most common Issues while registering devices with Microsoft Intune MDM

Image
  The built-in Mobile Device Management (MDM) for Office 365 helps you secure and manage your users' mobile devices like iPhones, iPads, Androids, and Windows phones. You can create and manage device security policies, remotely wipe a device, and view detailed device reports. During implementation or deployment, there are some common issues which occur in many of the environment  1-   Windows Update Sometimes you will notice that Windows Update is showing-Up-To-Date but in actual, the version needed for the MDM Registration is not updating automatically and eventually fails every time in the loop Solution Suggested Go to this  link  upgrade your Windows 10 to the latest version You will find a home page like the screenshot below. Click on UPDATE Now button. It will download a .exe file. Run the file and click on UPDATE Now button and press YES. Here it will update your Windows 10 to the Latest Version Note:  You can still work during downloading a...

Managing Windows Updates with Intune: Best Practices with Update Rings

Image
  Keeping Windows devices up to date is one of the most critical, and often most overlooked, aspects of endpoint security. With Microsoft Intune, you can manage Windows updates centrally using Update Rings , giving you control over when updates install, how users experience restarts, and how you test updates before broad deployment. In this guide, I’ll walk you through: What update rings are Why they’re essential for patch compliance How to configure them in Intune Best practices for rollout and user experience 1. What Are Windows Update Rings in Intune? Update rings in Intune allow you to: Define when and how Windows updates are delivered Set deadlines for installation and restarts Delay feature updates (e.g., to test before production) Control user experience during updates They apply to Windows 10 and 11 devices enrolled in Intune, including those provisioned via Autopilot. 2. Why Update Management Matters Without structured update management, you risk: Devices missing crit...

The Intune Device Lifecycle: From Onboarding to Retirement (Best Practices)

  Managing endpoints isn’t just about deployment, it’s about handling the entire device lifecycle : from onboarding and day-to-day management to secure deprovisioning when a device is no longer in use. Microsoft Intune provides a streamlined, policy-driven approach to each phase of this lifecycle, and when done right, it reduces IT overhead, increases security, and improves the user experience. In this post, I’ll walk you through the key stages of managing a device in Intune from start to finish, and how to handle each one effectively. Stage 1: Provisioning & Onboarding This is where the device journey begins, and it sets the tone for everything that follows. Tools and features to use: Windows Autopilot for zero-touch setup Enrollment Status Page (ESP) to control setup sequence Dynamic groups to assign configurations automatically Baseline security policies (compliance, Defender, encryption) Goal: Make the first experience smooth, secure, and consistent for every user.
