Modernization Case Study: How Refactoring Legacy .NET Apps Can Cut Operational Costs by 40%
Real-world proof that updating tech saves money.
The Challenge: Legacy .NET and Rising Costs
A mid-market enterprise was running critical business apps on legacy .NET Framework—on-premises, with manual deployments and high support costs. Scaling was expensive, and hiring for outdated tech was hard. They chose a phased refactor: modernize to .NET 6/8, move to Azure, and introduce CI/CD and monitoring. Within 18 months, operational costs (infra, support, and incident response) dropped by roughly 40%. The case study illustrates how targeted refactoring—without a full rewrite—delivers measurable cost savings and sets the stage for future AI and cloud-native features.
~40% Cost Cut
Operational costs reduced through modern runtime and cloud.
Phased Refactor
No big-bang; incremental modernization reduced risk.
Real Proof
Concrete numbers that justify modernization investment.
Lessons for Your Organization
Prioritize high-cost, high-pain systems first. Use modern .NET and cloud to reduce infra and support burden. Measure before and after so you can prove ROI. Dynotree has led similar modernizations—we can help you replicate this kind of result.
