Empowering Global Operations: Marsh McLennan’s High-Volume Multi-Country Migration with Xillio
Introduction
Marsh McLennan (MMC), the world’s leading professional services firm in risk, strategy, and people, embarked on a transformative journey to modernize its enterprise content management systems. With 83,000 employees across 130 countries, MMC supports a vast array of content processes, including account management, claims, policies, risk, and project documentation. Faced with the need to migrate 120 TB of content—comprising 200 million documents—spanning 10 countries, MMC turned to Xillio to ensure a seamless transition from OpenText Documentum to Microsoft 365.
Opportunity
MMC’s migration presented several unique challenges:
- Complex Data Landscape: Content hosted in two separate data centers (US and UK) with unique Documentum implementations for each country.
- Aggressive Timeline: A deadline driven by the expiration of costly Documentum licenses.
- Streamlined Collaboration: Decommissioning on-premises SharePoint 2013 and transitioning to Microsoft 365 for internal and external collaboration.
- Unified Compliance: Simplifying metadata and business logic to meet global auditing and compliance standards.
- Multi-Platform Integration: Incorporating additional migrations, including Meridio and custom applications built on Documentum.
Solution
Xillio deployed its advanced migration platform and tailored approach to manage the complexity and scale of MMC’s requirements:
- Centralized Unified Migration Database: Xillio’s tooling enabled all content and metadata from various Documentum repositories to be extracted, transformed, and tested before migration, minimizing errors and ensuring compliance.
- Custom Business Logic Design: Through workshops and user sessions, Xillio mapped metadata fields (300+), streamlined the hierarchy, and designed a migration strategy that met global and regional requirements.
- Provisioning and Testing: SharePoint Online sites were provisioned based on extracted data and tested rigorously, including alpha and delta migrations, to capture and migrate ongoing changes.
- Comprehensive Reconciliation: Full audit trails ensured transparency and confidence, providing end users with a detailed record of transformations.
- Seamless Scaling: Xillio took over additional project scopes from other vendors, showcasing its flexibility and capability to adapt to evolving project demands.
Results
Xillio’s meticulous execution and innovative platform delivered exceptional outcomes for MMC:
- Streamlined Operations: Migration of 120 TB and 200 million documents to Microsoft 365, enabling efficient and compliant global content management.
- Cost Savings: Decommissioning Documentum and SharePoint 2013 reduced hardware, license, and maintenance costs.
- Enhanced Collaboration: Transitioning to Microsoft 365 improved internal and external collaboration, supported by advanced features like Microsoft Teams.
- Future-Proof Platform: MMC is now positioned to explore opportunities such as Microsoft Syntex, Purview compliance tools, and Viva Topics for enhanced productivity and innovation.
Conclusion
MMC’s migration to Microsoft 365 demonstrates how organizations can successfully tackle large-scale, high-volume content transitions with the right expertise and tools. Xillio’s advanced platform and strategic approach ensured that MMC met its aggressive timeline while achieving a unified and modernized content management system.
