Delphi Migration

Over the years, Delphi applications have powered countless business-critical systems. However, many of them still run on older Delphi versions or outdated architectures that limit performance, scalability, and integration with modern platforms.

At Delphi Next, we expertly migrate Delphi application to latest version or technologies, while preserving core functionality and data integrity. Our team ensures a smooth, risk-free transition that minimizes downtime and guarantees continuity.

May it be migrating from Delphi 5, Delphi 7, or Delphi XE versions to the latest Delphi releases, or porting your Delphi system to .NET, web, or mobile platforms, we have the expertise and precision needed for a successful migration.

Our Capabilities

1. Version-to-Version Delphi Migration

We migrate applications from legacy Delphi versions (Delphi 5, 7, XE, etc.) to modern Delphi environments. This includes updating components, libraries, and dependencies while ensuring full compatibility with newer operating systems and frameworks.

2. Platform Migration (Desktop to Web / Mobile)

We help you extend your Delphi applications to web and mobile platforms using frameworks such as FireMonkey, or by creating hybrid and cross-platform solutions with Flutter or React Native — all while preserving your existing business logic and core functionality.

3. Database Migration

We assist in migrating databases from outdated systems to modern, scalable platforms such as MySQL, PostgreSQL, Firebird, SQL Server, or InterBase, ensuring data consistency, performance, and reliability throughout the process.

4. Technology Migration from Other Frameworks

Our experts also handle migrations from other development frameworks or programming languages — such as Visual Basic, .NET, C++ Builder, or legacy Pascal systems — into Delphi. This helps businesses consolidate their technology stack, improve performance, and simplify long-term maintenance.

5. Component & Third-Party Library Replacement

Outdated or unsupported third-party components can lead to compatibility and stability issues. We identify and replace them with modern equivalents. For example, updating or substituting legacy components such as TMS, FastReport, QuickReport, Indy, or DevExpress ensuring long-term stability, maintainability, and easier future upgrades.

6. Testing & Validation Post-Migration

We perform comprehensive functional and regression testing to ensure that your migrated application performs reliably and that no business logic is lost in transition.

Why Migrate Delphi Application?

A well-planned Delphi migration not only extends the life of your existing applications but also unlocks new opportunities for performance, integration, and scalability, without losing the business logic and reliability your teams depend on.

Compatibility with Modern Platforms:

Upgrading to the latest Delphi versions ensures full compatibility with current and upcoming Windows releases, as well as support for macOS, Linux, and mobile platforms through FireMonkey and other frameworks.

Improved Performance, Security, and Maintainability:

Modern Delphi compilers deliver faster execution, better memory management, and stronger security mechanisms. Refactored code and updated libraries also make your applications easier to maintain and scale.

Seamless Integration with Modern Technologies:

Migrated Delphi systems can easily connect with REST APIs, cloud services (AWS, Azure, Google Cloud), and modern databases such as MySQL, PostgreSQL, Firebird, and SQL Server, extending the application’s utility and connectivity.

Elimination of Deprecated Components and IDE Dependencies:

Legacy Delphi environments often rely on outdated or unsupported components. Migration helps replace these with actively maintained alternatives, reducing technical debt and ensuring smooth compatibility with newer toolchains.

Future-Proof and Scalable Architecture:

Modernized Delphi applications are easier to evolve, integrate with third-party tools, and deploy on multiple platforms, securing your software’s relevance and scalability for years ahead.
