About KPMG
KPMG operates at global scale, supporting a large and diverse workforce with strict security, compliance, and operational requirements. As part of its broader cloud strategy, the organization committed to retiring legacy datacenter infrastructure and modernizing endpoint management.
Windows11, Intune, and Azure Virtual Desktop were central to this strategy — but application risk threatened delivery timelines.
The Challenge
With over 250 Windows applications in scope and SCCM deeply embedded in existing processes, application readiness became the critical constraint.
Manual discovery and testing — delivered through an outsourced partner — could not scale to meet aggressive timelines. Each delay increased cost, risk, and dependency on legacy infrastructure.
KPMG needed a way to understand how applications would behave in a modern, cloud-managed environment before change was executed.
Solutions
Rimo3was introduced to replace manual, assumption-driven processes with evidence-based understanding and validation.
By automating application onboarding, testing, and modernization, Rimo3 gave KPMG clear visibility into readiness for Windows 11, Intune, and Azure Virtual Desktop.
Instead of discovering issues late, teams could validate application behavior upfront and move forward with confidence. The platform also laid the foundation for a Centre of Excellence, ensuring application change could be managed safely and predictably long after the migration completed.
Results
The impact was both immediate and strategic.
KPMG accelerated its Windows 11 and Intune program without increasing risk or headcount. Legacy infrastructure could be retired on schedule. Costs dropped. Delivery confidence improved.
What began as a time-bound migration evolved into a sustainable operating model for application lifecycle management — supporting evergreen updates, OS upgrades, and future initiatives such as Windows 365.
“Rimo3 automated the entire pipeline of testing, converting, and migrating hundreds of applications to Azure Virtual Desktop, Intune, and Windows 11. That level of validation accelerated our Intune migration dramatically and allowed us to deliver ahead of schedule while avoiding significant legacy infrastructure and third-party costs.”— IT Leadership, KPMG
Key Results:
- Eliminated months of outsourced manual testing, delivering significant cost and time savings.
- Kept SCCM and legacy datacenter decommissioning on schedule, avoiding ongoing infrastructure spend.
- Accelerated Windows 11 and Intune readiness, removing the primary modernization bottleneck.
- Established a repeatable, low-risk model for ongoing application change management.
- Enabled faster, lower-cost cloud migration aligned with KPMG’s global Azure strategy.
Conclusion
WithRimo3 embedded into its operations, KPMG now has a governed, repeatable approach to application change.
Modernization is no longer constrained by manual effort or late-stage risk. The organization can continue evolving its Microsoft workspace with confidence — validating change before deployment and scaling safely over time.
