Which Delphi versions are supported?

Ispirer supports the full range from Delphi 5 through Delphi 12.3 Athens — the current release as of 2026. The conversion engine is continuously updated to handle version-specific syntax, deprecated VCL components, FireMonkey frameworks, and legacy API dependencies across all major releases.

What target technologies are available?

Java, C# (.NET), Python, and VB.NET — each pathway purpose-built for specific enterprise priorities. Java for cloud-agnostic scalability, C# for the Microsoft ecosystem, Python for AI and data readiness, VB.NET for phased low-risk transitions. Ispirer's tool maps Object Pascal structures precisely to the idioms and conventions of each target language.

Can large, outdated Delphi applications be fully modernized?

Yes — and this is where automated conversion delivers its greatest value. Large Delphi codebases evolved over 20+ years typically contain deeply embedded business logic, undocumented component hierarchies, and complex database dependencies that make manual rewrites extremely high-risk. Ispirer Toolkit handles this scale accurately, regardless of application age or complexity.

What impact does the conversion have on system stability?

Pre-migration architectural assessment, automated validation against the original source, and CI/CD-integrated regression testing collectively guarantee that business logic behaves identically in the modernized environment. Zero-disruption deployment strategies ensure operational continuity at every stage. Your production environment is never placed at risk.

Is Delphi still used in enterprise environments?

Yes — and in significant numbers. According to Stack Overflow's 2025 developer survey, 2.5% of developers worldwide still use Delphi. It remains active across financial services, healthcare, logistics, and manufacturing — industries where mission-critical systems built in the 1990s and 2000s are still processing live transactions daily.

The challenge is not whether these systems work. It is that the talent pool maintaining them is contracting sharply, licensing costs are rising, and the architecture is fundamentally incompatible with modern cloud, API, and security demands. Enterprises acting now eliminate that compounding risk before it becomes a critical business liability.

What industries most commonly run legacy Delphi applications?

Financial services, healthcare, manufacturing, logistics, and education are the most common sectors. Banks and insurance firms use Delphi for transaction processing and risk assessment systems. Hospitals and clinics run Delphi-based patient management and laboratory software. Manufacturers rely on it for real-time production monitoring and quality control tools.

These are high-stakes, deeply embedded systems — exactly the environments where Ispirer's validated, zero-disruption conversion methodology delivers maximum value.

How is a Delphi modernization project initiated?

The process begins with a free assessment. Ispirer's team maps your full application inventory — components, dependencies, business logic, and database integrations — before any conversion begins. This gives you a precise timeline, automation rate estimate, and total cost of ownership projection with zero obligation. From there, you choose your target platform, and Ispirer handles the rest.
