AI-Assisted Modernization of a Legacy Mobile Platform

Migrating a Mission-Critical Xamarin App to .NET MAUI While Preserving Essential Functionality

A healthcare-focused organization relied on a long-standing Xamarin mobile application that gave medical professionals rapid access to critical treatment information. As the platform aged and support ended, the client needed to modernize the application while preserving essential functionality and avoiding a prohibitively expensive rewrite.

Art+Logic migrated the application from Xamarin to .NET MAUI through a phased, engineer-led process. The team broke the work into manageable pieces, using AI to assist with repetitive implementation tasks while engineers validated application behavior and critical workflows throughout the transition. This approach accelerated the migration while preserving the reliability and quality that medical professionals depended on.

The Challenge

The existing application had evolved over many years and contained extensive legacy code, specialized medical workflows, and platform-specific dependencies. Migrating from Xamarin to .NET MAUI was not a simple framework update; core libraries and application behaviors had changed significantly.

Early attempts to use generative AI as a wholesale migration solution failed. Large-scale automated conversion attempts produced builds that technically compiled but removed or disabled important application functionality in the process.

The team needed a safer, more controlled modernization strategy that could:

Preserve critical functionality
Reduce migration costs
Improve long-term maintainability
Minimize delivery risk
Modernize UX and feature sets simultaneously

The Solution

Art+Logic adopted a phased, AI-assisted modernization process that broke the migration into manageable pieces rather than attempting a full automated conversion all at once. Engineers rebuilt the application incrementally—reworking foundations, modules, interfaces, and workflows one layer at a time.

AI tooling was used strategically for repetitive, pattern-based coding tasks, dramatically reducing implementation time. However, developers maintained continuous oversight to validate logic, review generated code, and correct hallucinations or flawed assumptions introduced by the models.

This hybrid workflow allowed the team to:

Accelerate repetitive migration work
Preserve engineering quality standards
Reduce manual research and boilerplate implementation
Maintain architectural consistency
Avoid common AI-generated migration failures

The modernization effort also included a redesigned user experience and improvements to core workflows, ensuring the final product delivered measurable value beyond simple technical migration.

Key Enhancements



AI-Assisted Migration Workflow

The team developed an iterative migration methodology that paired AI-generated implementation support with human-led architecture, testing, and validation.



Intelligent Data Navigation

A complex medical reference tool was redesigned from a cumbersome scrolling interface into a filtered selection workflow that allowed users to quickly identify treatment options. Beta users responded enthusiastically to the improved experience.



UX Modernization

The application received a significant user experience redesign that streamlined workflows and improved usability for medical professionals operating in time-sensitive environments.



New Licensing Infrastructure

The project also introduced a new licensing and account-management platform, enabling digital license purchases and expanding the client’s operational capabilities beyond the original application scope.

Results

The modernization initiative delivered substantial gains in both development efficiency and product quality.

Results included:

Significant reduction in projected migration effort
Delivery hundreds of hours under budget
Full resolution of known legacy application bugs
Faster implementation cycles using AI-assisted workflows
Successful migration to a modern, supported platform
Expanded feature set and licensing capabilities
Reduced long-term platform risk and maintenance burden

Tasks that previously required multiple days of development could often be completed within hours when paired with effective AI-assisted engineering oversight.

Most importantly, the project demonstrated that AI can serve as a force multiplier for experienced engineering teams—accelerating modernization efforts without replacing the critical role of human expertise, architectural judgment, and quality assurance.
