[Day 2] Mission Intune : When Migration Becomes a Mission (Almost) Impossible
Good Morning Everyone 🕵️
Deep within the digital infrastructure, a high-stakes mission is being prepped. Five mobility experts have been deployed to solve a massive puzzle: migrating tens of thousands of smartphones to Microsoft Intune.
The Goal: Ensure a fluid, secure, and uninterrupted transition for thousands of users.
The Battlefront: A complex landscape filled with legacy policies, mixed configurations, and strict deadlines.
It’s a race against the clock where one wrong move could start a domino effect. From scripts to security protocols—nothing is left to chance.
Failure is not an option.
Following Broadcom’s acquisition of VMware in 2023, the Workspace ONE product is now owned by Omnissa. Broadcom’s commercial strategy, which has influenced its spin-off companies, had become highly aggressive toward all customers. Consequently, we have decided to migrate the management of our Android and iOS tertiary fleet to Microsoft Intune..
While we are familiar with Intune, several limitations should be noted:
- Reporting: Intune offers basic reporting through Microsoft Endpoint Manager and Power BI integration, but lacks the advanced, customizable dashboards available in Workspace ONE.
- Deployment Performance: Application and configuration deployments can be slow, with status updates often delayed due to Intune’s reliance on periodic device check-ins rather than real-time communication.
- iOS Management: Intune provides full functionality only for devices enrolled via Apple Business Manager (ABM). Non-ABM devices have restricted supervision capabilities, limiting advanced configuration and app deployment.
- Error Handling: Intune does not display granular error codes in its console. Troubleshooting often requires log collection from the device or use of Microsoft Support tools, increasing diagnostic complexity.
- Conditional Access & Compliance: Intune integrates tightly with Azure AD for conditional access policies, which is a strength, but requires additional configuration and licensing for advanced scenarios.
- App Protection Policies: Strong for Microsoft 365 apps, but less flexible for third-party apps compared to Workspace ONE.
Migration Strategy Overview
The project aims to migrate the entire mobile fleet—a few tens of thousands Android and some iOs devices—between September 2023 and December 2024. Cybersecurity requirements mandate a shift from COBO (with personal Google accounts allowed) to COPE, reinforcing corporate control and reducing exposure to security risks.
Key Challenges
- Technical Constraints: Devices incompatible with Android 13 require hardware replacement. For most employees, migration involves full device reset and Intune re-enrollment—a complex, time-consuming process.
- Security Limitations: Backup tools cannot be authorized, increasing the risk of data loss and user errors. A recurring issue is failure to remove Microsoft Authenticator configurations, creating significant support overhead.
- Performance Impact: The Samsung Galaxy A32, previously adequate under COBO, performs poorly under COPE, affecting user experience.
Status and Strategic Decision
By June 2024, progress is far below target. To mitigate operational disruption and support overload, the strategy shifts: forced migrations are discontinued. Migration now occurs only during:
- Hardware replacement (obsolescence, failure, or breakage)
- Voluntary device reset
This approach prioritizes stability and resource optimization while maintaining compliance with security standards.
We’ve been with Intune for almost two years, we make do with it and we are hardly surprised anymore when something doesn’t work.
