A leading global professional services firm operating across more than 65 countries needed to modernize endpoint management. Their legacy environment had evolved over many years—more than 100 active Group Policy Objects containing approximately 8,000 individual settings deployed across four global regions. Policy overlap was common. Deprecated configurations lingered. The AGPM deployment structure added complexity. And many legacy settings were simply unsupported by native Intune policies. The organization needed to transition to cloud-native management without disrupting end users across 65+ countries.
Royal Cyber partnered with the client to assess, rationalize, redesign, and migrate the entire GPO environment to Microsoft Intune. We analyzed every policy, removed duplicates and obsolete settings, re-architected security baselines, and rebuilt unsupported configurations using OMA-URI and PowerShell remediation scripts.
The result: 100+ GPOs modernized. 8,000+ settings migrated. Legacy policy estate streamlined. And zero major user impact during global rollout.
Legacy Policy Overload
More than 100 active GPOs containing over 8,000 individual settings had accumulated over years, creating significant management overhead and complexity.
Policy Duplication & Deprecation
Significant policy overlap, duplicate configurations, and deprecated settings existed across the estate, making maintenance difficult and increasing risk.
Complex AGPM Deployment Structure
Advanced Group Policy Management (AGPM) added another layer of complexity to an already challenging policy environment.
Legacy Settings Unsupported by Intune
Many existing policy settings had no native equivalent in Intune, requiring custom approaches for migration.
Multiple Active Directory Groups
Complex group structures needed synchronization and modernization to support cloud-native policy assignment.
Zero-Disruption Requirement
The migration had to preserve business continuity with no disruption to end users across 65+ countries during the transition.

Comprehensive GPO Assessment
Royal Cyber analyzed 100+ Group Policy Objects, approximately 8,000 policy settings, AGPM assignments, regional deployment structures, and policy dependencies to establish migration feasibility.
Policy Rationalization & Cleanup
Identified duplicate policies, deprecated configurations, and obsolete settings. Consolidated overlapping controls and obtained stakeholder approvals for policy retirement—significantly streamlining the policy framework.
Intune Migration Path Categorization
Using Microsoft's Group Policy Analytics, categorized policies into migration paths: native Intune policies (Settings Catalog, Administrative Templates, Security Baselines), custom configuration profiles (OMA-URI), application-based configurations, and PowerShell remediation scripts for unsupported settings.
Security Baseline Re-Architecture
Redesigned endpoint security posture from scratch—separating baseline controls from operational policies, re-architecting using Microsoft Intune Security Baselines, and aligning controls with Microsoft best practices.
Identity & Group Modernization
Synchronized Active Directory groups with Microsoft Entra ID, recreated missing cloud groups, redesigned policy assignment structures, and translated AGPM deployment logic into Intune assignment models.
Phased Global Rollout
Executed structured deployment sequence: pilot countries, smaller country deployments, larger country deployments, regional rollouts, and global production adoption—incorporating lessons from early waves into subsequent migrations.
