Migration Pattern
Why move from Delphi to Java?
・Delphi will eventually be migrated to other technologies.
・Let’s proceed with modernization while you can, including learning Java, to prepare for a swift transformation.
Continuing to struggle with outdated technologies when updates are eventually needed is not a wise strategy.
Features of Our Conversion Service
Our proprietary language migration and conversion tools boast industry-leading accuracy and a proven track record.
Our inimitable technical capabilities, along with numerous successful cases, ensure the success of the migration projects.
Features of AppModernizer’s Automatic Conversion
Achieves extremely high quality, low cost, and high maintainability, while also enabling integration with other Java platforms.
Testing for Superior Quality with Fewer Man-Hours
Instead of relying on customer-provided test data for quality assurance, we conduct comprehensive testing of all technical points and critical business processes to significantly reduce testing time.
High Quality and Low Cost than Manual/Semi-Automatic Conversion
※¹ This is mainly a fine-tuning of the screen and report UI, and does not affect business logic.
※² “Software Development Analysis Data Collection 2022” relased by the Information-technology Promotion Agency of Japan states the number of defects after
release is 0.084 to 0.1 per thousand lines of code (KL). We use this figure as our standard to follow.
※³ Since business logic processing can be converted almost 100% automatically, the number of defects in the business logic portion is extremely low. Minor issues
such as display position issues or lack of focus may occur depending on the screen display or operation, but this will not affect the use of the system.
Samples of AI-powered Language Conversion
①Moving to standard Java structure (for example, Spring MVC)
Spring Boot (MVC) simplifies the development process with its straightforward configuration, modularity, and other key features
②Generating pure Java code
Generating pure Java and applying the latest Java technology standards simplify maintenance and specification changes.
UI migration
Change the Delphi screen to a standard HTML5-based web screen

Q&A
After migrating from Delphi to Java, how should third-party products such as GKitOCX Spread be migrated?
To ensure future maintainability, we are opting to implement functions equivalent to those of the current system using standard front-end frameworks like HTML and Vue.js, rather than relying on alternative third-party products.
