Let us help you rebuild what’s holding you back.
Corsac experts provide tailored migration strategy that replaces legacy software with scalable, future-ready solutions. We help your business move in the way you want it, not as your software dictates.
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.
Cobol systems run on outdated mainframes where even minor failures require slow, expensive, and unpredictable recovery, putting business continuity at risk.
Businesses that rely on legacy COBOL apps lose competition to agile competitors, which modern software, unlike COBOL, support mobile, real-time alerts, and API onboarding.
COBOL systems rely on decades of undocumented logic, making them dependent on one or two senior developers. One retires, and you lose control over the entire system.
COBOL workloads can’t adapt to increasing data volumes. Businesses choose COBOL migration services because they are done with missed growth opportunities, as their system doesn’t scale.
COBOL systems do not provide sufficient logging, tracing, and monitoring. Engineers who fix bugs operate blindly, spending efforts on maintainability, not COBOL modernization.
Implementation of each new feature requires navigating dense and outdated COBOL code. Migrating critical logic to С# helps facilitate new feature releases, speed up the entire pipeline, and decrease regression risks.
We tailor our COBOL migration services to solve the specific goals of each organization that relies on aging COBOL software.
During COBOL modernization, we move systems from aging infrastructure to stable cloud environments while preserving core business logic. A modernized software is resilient, cheaper, and easier to maintain compared to legacy hardware.
We refactor large COBOL programs into smaller, well-structured modules, with clear, consistent interfaces. This enables us to reduce regression risk, ease maintenance, quicken onboarding for new developers, and set a cleaner foundation to modernize partially or extract services in steps.
Corsac rebuilds the old COBOL system from scratch using modern languages like C# and cloud-native tools. We pull out, check, and rewrite business rules with proper APIs, CI/CD, and observability so the system can evolve and support future digital products.
Keep stable COBOL cores but expose capabilities through APIs and events. New features and analytics run on modern platforms, reducing risk with incremental offloading instead of a single big-bang rewrite.
Successful migration begins with understanding your starting point. We combine automated tools with manual analysis to capture both technical quality and business-critical risks
Keeping in mind your business objectives, our team develops a tailored modernization roadmap. We select target architecture (microservices, cloud-native, hybrid), migration model, and technologies, suitable platforms and technologies, and determine the most efficient migration approach.
Thoroughly assess systems to uncover and resolve hidden issues before they accumulate.
Optimize performance and build seamless integrations to eliminate legacy barriers.
Prepare applications for AI adoption and compatibility with emerging technologies.
Integrate modernization with workflow tools for visibility, testability, and traceability.
Provide transparent project management with regular demos and check-ins to track every stage of transformation.
Following a successful migration, we keep the system fully functional and tested. We utilize your Git, CI/CD, and tools while working independently. Corsac developers validate the system’s reliability in the new environment, letting your team focus on their work.
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.
COBOL is a high-level but legacy programming language. You need COBOL migration services if you face rising maintenance costs, lack of vetted specialists, security risks, and integration restrictions. This is an ideal choice for organizations looking for scalability and digital transformation opportunities.
Replacing COBOL is the process of moving applications from COBOL to modern programming languages such as Java, Python, C#, etc.through code modernization and gradual migration. You can either improve existing COBOL systems or opt for a full rewrite.
We prefer the word outdated. COBOL is not a dead language since it’s still used for banking, insurance, and government systems. However, COBOL software is limited in innovations and integrations while also being expensive to maintain. This is why COBOL software modernization services are in a high demand now.
Migrating COBOL applications to modern languages resolves a set of business and technical issues for organization. As a result of COBOL transformation, you lower long-term support costs, reduce reliance on scarce COBOL expertise, and make systems easier to scale on cloud and microservice architectures.
Migrating COBOL to Java reduces reliance on costly legacy expertise and makes maintenance easier and budget-friendly. Java is known for vast developer ecosystem, platform independence, and strong integration capabilities that allows businesses deploy modernized systems across cloud or hybrid environments, scale with ease, and integrate seamlessly through APIs and microservices.
