Workflow
Strategic Multi-Phase Legacy Upgrade
The approach involved a series of strategic upgrades: Ruby and Rails upgrade, introducing advanced features, and the adoption of the Deprecation toolkit.
Phase 1
Major version upgrade
Transitioned from Ruby on Rails 4.2 to 7.0, and Ruby from 2.6.3 to 3.0. This move addressed approximately 60 security issues and provides access to the latest improvements.
Phase 2
Feature enablement
The upgrade facilitated access to advanced functionalities like real-time communication, enhanced security, more efficient memory usage, and improved web performance.
Through careful modernization of a mission-critical legacy platform, we transformed technical debt into a stable, future-ready foundation—enabling secure scaling, faster innovation, and long-term engineering confidence.
Solution
Multi-Phase Upgrade and Code Health Implementation
The modernization strategy was implemented across three concurrent pillars: version migration, advanced feature unlocking, and the creation of sustainable code quality processes.
Deprecation toolkit adoption
To manage the continuous cycle of deprecations, the team implemented the Deprecation Toolkit.
Code quality management
This tool improved deprecation visibility and management, helping maintain code quality and consistency.
Results
Reinforcement of Security and System Scalability
The extensive upgrades have greatly enhanced the system’s capabilities.
60 critical flaws eliminated
The comprehensive upgrade from obsolete frameworks to Ruby 3.0/Rails 7.0 significantly reinforced the security infrastructure, directly eliminating approximately 60 critical security issues that were exposing the core construction management platform.
Stability and scalability boost
The migration to the latest frameworks unlocked advanced features and more efficient memory usage, leading to a considerable improvement in the application’s overall robustness and scalability for the cloud-based system.
New feature enablement
Access to modern language features and frameworks facilitated the introduction of advanced functionalities like real-time communication, enhancing overall web performance and future development agility.
Business Value
Enabling Continuous Code Health and Team Efficiency
