Timing Matters

Top Signs Your Business Should Have Migrated from Delphi to .NET

Too costly software maintenance as legacy support drains budget, reduces efficiency, and limits funds for innovation.

Your key staff is overwhelmed and exhausted because of fixing recurring issues.

As Delphi ages, qualified developers are harder to find, development of new features becomes challenging and expensive.

System failures and downtimes keep escalating, as even one obsolete part can lead to overall instability.

Integration with modern technologies and services is limited, causing functionality gaps.

Delphi to .NET Migration Case Studies

With Delphi rewrite, we ensure mainframes remain modern, secure, and smooth running. Backed by 17 years of experience, we tackle issues at the root, deliver compliance-driven modernization and enable innovations.

Comprehensive Delphi Migration Services for Modern Application Optimization

Quick patching is not our approach. While providing Delphi to .NET migration, we uncover underlying issues, eliminate hidden tech debt, and deliver resilient, future-ready solutions.

Legacy Code Assessment & Audit

We start with thorough assessment of your system logic, identify duplicated code, outdated protocols, compliance gaps, security risks and other bottlenecks to ensure safe migration without unpleasant surprises.

Architecture Redesign & Modernization

We break your monolithic Delphi architecture into modular components that are easy to manage and update. From code refactoring to database upgrades and connectivity enhancements, we ensure smooth modernization for growth and long-term stability.

Automated & Manual Code Conversion

We combine automated tools and manual refinements to speed up legacy code conversion, preserving high accuracy, clarity, alignment with overall business logic and performance standards.

Database & API Migration

We move data to modern SQL/NoSQL systems and rebuild legacy APIs into secure REST/gRPC services, preserving data integrity and workflow consistency, as well as compatibility with .NET ecosystem.

UI/UX Modernization

We transform clunky Delphi forms with rigid layouts, confusing navigation and outdated design patterns into responsive, accessible, intuitive interfaces, optimized for cross-device experience.

Testing, Deployment & Support

Outdated Delphi apps usually suffer from poor test coverage, slow release cycles, and patch-heavy support. We apply CI/СD pipelines, automated validation, and ongoing tech support to ensure reliability and streamlined time-to-market.

Full-Cycle Delphi Migration Services for Seamless Transformation

Step 1. Discovery & Strategy Planning

We start with a deep analysis of your Delphi environment, inspecting fragile modules, hidden dependencies, architectural logic, as well as detecting root causes of tech stagnation and potential risks. Next, we build a detailed migration strategy fully aligned with your business priorities.

Step 2. Proof of Concept (PoC)

We test the technical viability of your Delphi to .NET migration by extracting selected components and conducting code conversion. We check performance, compatibility, UI/UX, security level and other important aspects in a controlled environment.

Step 3. Incremental Migration Execution

1) Outdated system decomposition
2) One-by-one moving of modules to .NET with ongoing stability and performance validation
3) Controlled parallel running of old and new components to ensure uninterrupted workflow
4) Adoption of .NET-native safeguards (OAuth2, TLS) to strengthen security
5) Embedding of modernized modules into CI/CD pipelines for automated validation and rapid deployment

Step 4. Knowledge Transfer & Post-Migration Enablement

We provide your team with comprehensive documentation and guidance to work with upgraded software confidently and independently. With our hands-on training and continuous post-migration support, you’ll be fully equipped to scale, integrate, and innovate.

What Makes Corsac a Trusted Partner for Delphi Migration Services?

Modernization is our core specialization

We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.

Integration vs. Disruption

We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.

Identification of hidden expenditures

Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.

Respect for Existing Architecture and Leadership

We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.

Fighting Tech Stagnation

Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.

AI & Emerging Tech EnablementAI & Emerging Tech Enablement

We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.

FAQ

  • Absolutely. We conduct Delphi migration incrementally. It means that we decompose large monoliths into separate modules one by one, testing overall system stability and performance at each step. At the same time we ensure parallel running of other, not modernized yet, parts of the system. Your critical workflows will remain stable with zero downtime.

  • Yes. As part of a Delphi rewrite, we modernize both inner app architecture and its interface. The outdated Delphi systems usually suffer from clunky layouts, lack of accessibility, and poor user experience. We redesign your app providing seamless navigation, high cross-platform adaptability, and sleek modern look.

  • Sure. After Dephi to .NET migration, your codebase is well-documented and easy to maintain. We provide all the necessary guidelines, continuous support and team trainings to make sure that your experts can operate the system without any problems, as well integrate new tool and scale in accordance with your evolving business needs. 

  • Yes. PoC is a perfect way to de-risk the Delphi to .NET migration. We test code conversion and performance of critical modules, check database connectivity, UI/UX improvements in .NET environment before full rollout. This way you can move forward with confidence, ensuring smart allocation of budget and time-efficiency.

  • Absolutely. Our key priority is to ensure functionality modernization while keeping its key logic. We validate each module with automated and manual testing to make sure that the upgraded .NET system behaves identically with the original, and all integrations and critical data are preserved.
