Modernizing Precision Dispatch: Migrating Legacy Architecture to Scalable Microservices

From Monolithic Constraints to Modular Modernization

In industries where precision and reliability define performance, legacy systems can become both the backbone and the bottleneck of innovation. Over time, tightly coupled architectures, outdated languages, and manual processes begin to limit scalability, agility, and the ability to evolve at market speed.

A global transportation technology leader faced this challenge with its Precision Dispatch platform—a mission-critical system spanning more than 15 interdependent modules responsible for managing complex scheduling, routing, and operational logistics.

Built on an aging C++ architecture, the system had become increasingly difficult to scale, maintain, and integrate with newer digital tools. To ensure long-term efficiency and innovation, the organization needed to migrate to a modern Java-based, microservices-driven framework—while enhancing functionality, introducing automation, and standardizing design across multiple user interfaces.

The Challenge:

Modernizing a Multi-Module Legacy Platform

The client’s dispatch management platform had evolved over time into a complex ecosystem of legacy code, disparate interfaces, and manual testing frameworks.

Key modernization challenges included:

Legacy Dependencies:
The C++ codebase limited scalability, slowed feature delivery, and hindered interoperability with modern systems.
Frontend Inconsistency:
Each module had evolved independently, resulting in fragmented UI patterns and inconsistent user experiences.
Manual Testing Limitations:
Time-intensive manual QA processes slowed releases and increased the risk of undetected regressions.

The organization needed a modernization strategy that would re-architect core systems, standardize the user experience, and embed automation—all without disrupting critical operations.

The Solution:

End-to-End Platform Modernization

Aditi Consulting partnered with the client to deliver a fully managed modernization engagement, applying its Legacy Modernization Framework to transform the dispatch platform into a scalable, modular, and automation-ready ecosystem.

Through a combination of technical assessment, roadmap definition, and phased execution, Aditi conducted a comprehensive audit of the existing legacy systems to identify modernization priorities, defined a transformation roadmap aligned with operational and architectural dependencies, and applied its proven modernization accelerators to streamline migration and integration across the platform.

Modular Migration to Java 11
Aditi’s engineering team executed a structured migration from C++ to Java 11, refactoring more than 15 legacy modules into a cloud-ready microservices architecture designed for scalability, reusability, and long-term maintainability.
- Established modular codebases to enable independent service deployment and version control
- Introduced microservices design principles to decouple core functionalities and simplify future enhancements
- Enabled integration readiness with analytics, automation, and emerging digital tools
- Reduced technical interdependencies to minimize complexity in ongoing development cycles

Frontend Standardization & Design System
Modernization extended beyond backend systems to unify the platform’s visual, interaction, and component layers, enabling design consistency and streamlined front-end development.
- Developed cross-library components using native web components for interoperability across modules
- Established a centralized Design System to standardize UI patterns, branding, and accessibility standards
- Introduced shared component libraries to accelerate interface development and ensure visual consistency
- Aligned design and development workflows to promote collaboration between UX and engineering teams

Automation-Driven Testing Infrastructure
To modernize quality assurance and reduce manual effort, Aditi implemented an automation-first testing framework integrated into the CI/CD pipeline. This created a continuous, reliable validation layer across development and deployment stages.
- Transitioned manual test suites into automated regression and integration test pipelines
- Implemented continuous testing aligned with DevOps best practices
- Expanded test coverage to improve visibility across service-level interactions
- Integrated automated validation into the release process to ensure quality consistency and deployment readiness

The Outcome:

From Legacy to Modern Dispatch
