Delphi Migration for a Large Enterprise
Delphi 5, Delphi 11 | MongoDB, Firebird
Client's Industry
Fintech, South Africa
Challenge
The client relied on a legacy document processing and workflow management system built in Delphi 5. The system had frequent crashes, poor compatibility with modern Windows environments, and was increasingly difficult to maintain due to outdated components and third-party libraries. Additionally, the client’s IT team faced challenges onboarding new developers as the system’s complexity grew.
Solution
We successfully migrated the client’s Delphi 5 application to Delphi 11 Alexandria. This involved reviewing and refactoring over 800,000 lines of legacy code, replacing outdated components, and upgrading third-party libraries. We ensured full compatibility with Windows 10 and above and introduced automated unit testing and version control to streamline future maintenance.
Result
- 60% reduction in runtime-related support tickets
- 40% performance boost in application speed and reliability
- Improved developer efficiency with modern Delphi tools, reducing onboarding time
- Enhanced system stability and future-proofing for scalability
