Delphi to Java Migration

SoftRoad has helped many customers migrate legacy Delphi systems to modern technologies such as Java. Using our proprietary AI-assisted conversion technology, supported by structured analysis, validation, and engineering review, we migrate legacy Delphi code and data to pure Java systems that fully comply with industry standards. The resulting systems are rigorously tested for superior quality, highly maintainable, and generative AI–ready for future maintenance and enhancement.

Why move from Delphi to Java?

Delphi will eventually be migrated to new technologies.
Modernizing your Delphi system early, while your in-house teams still retain the skills and knowledge of the legacy system, can better support the migration process and reduce overall migration costs.
Operational and modification expenses will also be reduced after migration.

Features of Our Conversion Service

Our proprietary, rule-based, AI-assisted conversion tool accurately understands Delphi system components and produces pure Java systems comparable to those built by human programmers, delivering higher quality and lower costs, as proven across many past projects.

Features of AppModernizer’s Automatic Conversion

AppModernizer converts legacy Delphi systems to the latest mainstream technologies and also provides the following advantages in the new system.
☛ Generate standard Java code and migrate to new framework .
☛ Adopt new DB, OS, middleware.
☛ Implement multi-device support.
☛ Migrate to cloud, etc.

AppModernizer ensures remarkably high quality, low costs, and high maintainability, while enabling integration with other Java platforms.

Testing for Superior Quality with Fewer Man-Hours

Instead of relying solely on customer-provided test data for quality assurance, we conduct test that covers all technical points and critical business processes to rigorously ensure quality and reduce test cost.

Remarkably High Quality and Low Cost Compared to Rewriting

※¹ This is mainly a fine-tuning of the screen and report UI, and does not affect business logic.
※² JUAS (Japan Users Association of Information Systems) states that the industry-standard post-release bug rate is 0.084 to 0.1 per thousand lines of code (KL).
※³ Since business logic processing can be converted with automation, the number of defects in the business logic portion is extremely low. Minor issues such as display position issues may occur, but this will not affect the use of the system.

Samples of AI-powered Language Conversion

①Change program structure from Delphi to Java

②Generating pure Java code

Modernizing to pure Java and the latest Java technology standards is important for maintenance and improvement.

UI migration

Change the Delphi screen to a standard HTML5-based web screen

Delphi Upgrade

When modernizing a legacy Delphi system, if the budget is limited and only a few future modifications are expected, Delphi upgrade may be a suitable option.
