Timing Matters

Top Signs You Should Have Started Mainframe Modernization Yesterday

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Outdated technologies used in your software compromise security and regulatory compliance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

Mainframe Modernization Case Studies

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.

How Mainframe Modernization Helps Overcome Key Legacy Challenges

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.

From Business Perspective

● 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

From Technical Perspective

● 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● Outdated security and hidden vulnerabilities pose the risk of breaches and incompliances

Let’s schedule a 30-minute call to discuss your challenges

End-to-End Mainframe Modernization Services for Application Optimization

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.

Legacy Application Assessment & Audit

We start with consultancy and a comprehensive check of your system to address stagnation at the root instead of applying surface-level fixes. Thus, we reveal and solve the invisible costs of legacy tech before they show up.

Mainframe Application Re-Engineering

We preserve fundamental business logic while eliminating bottlenecks like COBOL rigidity or monolithic dependencies. Focusing on overcoming aging systems, we transform modernization from an engineering problem into a leadership asset. 

Mainframe-to-Cloud Migration

We help you experience the rich benefits of cloud infrastructure, including scalability and security. Without any interference in your team’s work, we move your legacy applications to a cloud environment, empowering agility, efficiency, and continual innovation.

System Integration & API Enablement

With the core focus on innovative data management, our team connects your legacy systems with modern platforms through secure, efficient APIs. It helps overcome data silos and slow workflows, promoting smooth data exchange and smart business operations.

UI/UX Modernization

We revamp outdated interfaces into intuitive and friendly designs that drive usability and ensure accessibility compliance. Role-based dashboards further reinforce convenience and improve workflows.  

Ongoing Support & Optimization

We do more than just modernizing code. We ensure your company is ready to implement new tech breakthroughs. As such, our approach includes continual proactive monitoring, fixing security, and optimizing performance for uninterrupted, resilient performance.

Full-Cycle Mainframe Modernization Services for Seamless Transformation

Step 1. Discovery & Legacy Assessment

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. 

Step 2. Modernization Strategy & Architecture Design

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.

Step 3. Implementation & Integration

● Mainframe systems modernization at Corsac is handled by senior-level engineers, independently from your in-house team● We utilize advanced code refactoring and reengineering techs, including modular architecture and CI/CD● Adaptive planning with regular demos and status updates guarantee transparent processes and significant results● A progressive delivery approach allows for phased rollouts and minimal business risk
Hands-on support even after release ensures resilient operation, feature upgrades, and expert guidance
● Hands-on support even after release ensures resilient operation, feature upgrades, and expert guidance

Step 4. Testing, Deployment & Knowledge Transfer

We ensure your mainframe operates at its peak performance and train your staff on the new system. Prioritizing smooth adoption and long-term maintainability, we keep consulting and upskilling your team.

What Makes Corsac a Trusted Provider of Mainframe Modernization 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.
