Delphi to Java Migration
Corsac converts Delphi to Java while development continues in parallel. We refactor the architecture and address the typical legacy issue where Delphi logic is buried in forms, event handlers, and Windows-bound components.
We deliver predictable releases and help reduce technical debt early, before it starts to slow teams down or impact revenue.

Your Delphi desktop apps break when Windows updates or hardware changes.
Your team’s key talent faces burnout with constant fixing
Your Delphi architecture limits integrations with APIs, ERP, BI as well as cloud and AI adoption.
Your Delphi systems miss modern encryption and logging required for compliance under GDPR, HIPAA, SOC2, or ISO.
You spend the budget on maintenance and bug fixing, not innovating
For over 18 years, the Corsac team has helped convert Delphi to Java systems across GIS, construction, healthcare, AI, media, and others. We specialize in controlled modernization of desktop-heavy, UI-bound legacy systems into maintainable, future-ready Java architectures.

38%Our Delphi to Java migration services expose “dark tech debt” that drains your budget, such as UI coupling, undocumented rules, and brittle binaries.
Remove Windows lock-in without stopping daily operations
Cut modernization risk with phased migration, not a big bang
End release freezes caused by brittle Delphi components
Improve hiring and vendor options by moving to the Java ecosystem
Lower hidden maintenance costs from patches and outdated tools
Open new channels: web access, remote use, integrations, analytics
Give leadership a clear roadmap with predictable milestones
Pull business logic out of the Delphi UI into Java services
Replace COM/ActiveX with Java libs, vendor APIs, microservices, or events
Shift to an API-first design (REST or GraphQL where suitable)
Add structured state management (stateless services, defined sessions)
Standardize transactions, errors, and system observability
Modernize data access with ORM/DAO and tuned queries
Set up CI/CD, test coverage, and incremental releases
Let us help you rebuild what’s holding you back.
Our approach relies on incremental, parallel migration, allowing Delphi and Java coexist with minimum disruption. Corsac team plugs into your Git workflow, CI/CD setup, security rules, and release rhythm and operates with minimal load on your in-house team.
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.
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.
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.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
We analyze Delphi forms, modules, VCL usage, COM/ActiveX links, data flows, and undocumented logic. Based on data received, we form a report that defines what must be preserved, refactored, or replaced before Java work begins.
We extract business logic from forms and event handlers and rewrite them into Java services and libraries. This removes hidden coupling, global state, and order-sensitive logic but keeps consistent and verifiable performance.
Migrate VCL/FMX interfaces to WinForms, WPF, or MAUI, aligned with your product’s lifecycle.
Separate UI from business logic to support future UX changes without breaking workflows.
Replace embedded SQL with structured, maintainable data access layers.
Add REST APIs to integrate with ERP, BI, and other external systems.
Implement async processing and modern, secure authentication methods.
We document the new structure, explain architectural decisions, test behavior before release, and innovate incrementally. Corsac team transfers knowledge to your developers so they can maintain and extend the Java system without relying on us long-term.
Book an expert consultation to uncover gaps in your system. Let us modernize your business to its maximum potential.
We focus on modernization for companies unable to grow due to aging systems
We replace only what must be changed, protecting your investment and CTO’s credibility.
HIPAA, HL7/FHIR, SOC2, GDPR, ISO compliance is integrated into every stage.
Integrating into your Git, CI/CD, and workflow tools, we make modernization visible, testable, and traceable
We uncover hidden costs, feature delays, and security gaps and offer ways of their removal
By providing CEOs stakeholder-ready roadmaps and progress metrics, we enable well-grounded transformation
They fulfill your task without seeking to address the issue at the root
Dispersing the focus, they fail to meet specific Healthcare G and other industry requirements
Generalized practices, regardless of the product, team, or business specifics
Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
Delphi apps rely on Windows desktops, fragile components, and tightly coupled code. Migrating to Java removes platform lock-in, reduces hidden maintenance costs, and opens new channels like web access, integrations, and analytics. We keep your workflows stable and your systems secure and compliant.
Corsac team follows an incremental, parallel approach. Delphi and Java systems run side by side, so operations continue uninterrupted. Releases stay predictable, and modernization happens in phases, always with a rollback option. With us, migration is never a risky “big bang.”
Corsac integrates into your Git workflow, CI/CD pipelines, security policies, and release cadence. We convert Delphi code independently while documenting and transferring knowledge so your engineers can maintain and evolve the system post-migration.
Yes. We migrate Delphi VCL/FMX UIs to modern Java frameworks (desktop, mobile, or cross-platform) while decoupling business logic from the interface. The result is a maintainable UI that remains familiar to your users and evolves without breaking core business rules.
Our Delphi to Java migration services are not only updating the code but rethinking the processes that hold your business back. With over 18 years of experience, we have been creating applications that easily scale. We foster independent maintenance, but if you need post-release support, our team is always here to help.
