High operational costs vs. limited agility: you invest in maintaining legacy instead of adopting innovations
Your mainframe causes data silos, impeding data sharing and operability
You cannot break through technical constraints: resources are spent on routine maintenance, not on innovations
Outdated technologies used in your software compromise security and regulatory compliance
Your critical talents are overloaded and burnt out due to continual issue fixing
We keep mainframes up to date, secure, and resilient to ensure that all your processes run smoothly. 17 years of experience and narrow specialization help us remove the issues at the root, combine modernization with compliance, and enable breakthrough tech adoption.

We restore your ability to grow with mainframe modernization and integration. We fix what you see – slow, brittle code – and what you don’t see – poor development processes and a lack of innovation culture.
Mainframe data cannot be integrated with modern systems, hindering decision-making
Black-box logic and undocumented APIs hamper flexibility
Spaghetti code and monolithic architecture block business growth
Outdated security and hidden vulnerabilities pose the risk of breaches and incompliances
Modernization helps reduce high infrastructure and maintenance costs and drive agility
Effective resource allocation with innovations in mind
Faster implementation of competitive upgrades
Lower team burnout with the focus on strategic tasks
Let us help you rebuild what’s holding you back.
Our practical approach to mainframe modernization and integration respects your existing investments. We maximize the use of on-premises and cloud environments in private and public clouds to achieve outstanding results.
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.
At project kickoff, we start by understanding your business goals, constraints, and risks. This allows us to prepare a modernization readiness report that defines what must change to ensure long-term stability and scalability. We don’t modernize for the sake of technology; we modernize to restore your ability to grow.
As part of our mainframe migration services, we analyze how the system was built, how it evolved, and how it is maintained today. We examine code ownership, undocumented logic, release and deployment practices, operational risks, and team dependencies. This helps eliminate hidden weaknesses and prevent threats before they disrupt trust, rhythm, or reputation.
Before mainframe modernization service actions begin, you receive a clear, structured report describing the current state of your system, identified risks, and improvement opportunities. Our goal is to help you invest in innovation instead of maintaining outdated technology.
Based on audit findings, we build a realistic roadmap with short-term and long-term steps for modernization. We integrate into your team and workflows, ensuring no disruption, just progress. Each roadmap is tailored because every legacy mainframe system is unique.
When your priority is reducing hardware risk fast, we rehost mainframe workloads with minimal logic change. This approach stabilizes operations and creates a safe starting point for mainframe systems modernization without breaking business workflows.
If you want to reduce operational overhead but preserve core behavior, we move applications to managed runtimes and modern platforms. Our mainframe modernization and integration approach lowers infrastructure burden while keeping system reliability intact.
For long-term maintainability and access to modern talent, we refactor mainframe logic into modern stacks. We don’t just modernize code, we restore your ability to scale, evolve, and invest in innovation instead of legacy upkeep.
When full replacement is too risky, we extract functionality step by step into modern services. We integrate new capabilities around your mainframe core, preserving trust, delivery rhythm, and business continuity.
If releases are slow and risky, we modernize deployment models, introduce CI/CD, and stabilize environments. This removes friction, reduces operational risk, and prepares your system for continuous improvement.
We carefully inspect your mainframe legacy systems and conduct clear mainframe-specific checks, including codebase, performance, and integration bottlenecks. This stage uncovers what’s holding you back – tech debt, limited scalability, or security risks.
We develop a structured modernization plan, offering options for your choice. When building architecture, we aim to reinvent monolithic design, obsolete frameworks, and unmaintained dependencies.

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.
Mainframe modernization service entails removing legacy constraints and adapting your mainframe applications to a more advanced tech stack. As a result, your mainframe becomes easier and less expensive to operate and support, offers wider integration opportunities, and empowers innovation and growth.
Corsac offers tailored mainframe modernization solutions, reinventing vast kinds of apps. The areas we handle include order processing, transactions and inventory control, medical patient record systems, construction mapping systems, and more. We specialize in 7+ niches, including healthcare and GIS, helping companies become stronger.
The duration of mainframe modernization and integration depends on the project scope and requirements. Engineers shape the timeline based on the current tech stack, application complexity, modernization approach, data migration needs, and other parameters. While small upgrades can take about 3-6 months, large undertakings like complete re-platforming can last for a year or more.
Corsac’s mainframe consultants can describe all potential risks and our mitigation measures in detail. The primary threats to consider include extra expenses, postponed deadlines, failure to meet goals, and degraded performance and features. We prevent these occurrences through our keen expertise, transparent processes, and the ability to fix the issue at the root.
Corsac’s approach to mainframe systems modernization prioritizes uninterrupted business operations with minimal interference with your team. Moreover, your engineers become relieved from the need to repeatedly fix outdated software. Our modernization is focused on growth and innovations to ensure business continuity. Your team becomes more efficient and your business – more powerful.
