Global Manufacturer Modernizes Core ERP with SAP S/4HANA on Azure
Industry: Manufacturing | Client: A Fortune 500 industrial goods manufacturer.
Client Overview: The client was running a highly customized, 15-year-old SAP ECC system on-premise. It was slow, expensive to maintain, and could not provide the real-time data needed for smart factory initiatives. They needed to move to S/4HANA to stay competitive but were concerned about the risk of disrupting their global supply chain operations.
"CIS was more than a vendor; they were a true partner. Their deep expertise in both SAP and Azure was critical. The migration was smoother than we ever imagined, and we're now seeing data insights that were previously impossible." - Xavier Frost, CIO
Key Challenges:
- Migrating over 10TB of data with zero downtime.
- Remediating thousands of custom ABAP objects for S/4HANA compatibility.
- Integrating the new ERP with dozens of legacy factory floor systems.
- Training over 5,000 users across multiple continents on the new system and FIORI UX.
Our Solution:
We executed a Bluefield migration, selectively moving historical data while implementing new S/4HANA processes. Our AI-powered code analysis tools automated 70% of the ABAP remediation, and we built a modern integration hub on Azure to connect to factory systems.

Regional Bank Replaces IBM Mainframe with Cloud-Native Core Banking Platform
Industry: Banking & Financial Services | Client: A mid-sized regional bank with $20B in assets.
Client Overview: The bank's core transaction processing system ran on an IBM z/OS mainframe. The high licensing costs, scarcity of COBOL developers, and inability to launch new digital products quickly were hindering growth. They needed a modern, agile, and scalable platform to compete with fintech startups.
"The thought of touching our mainframe was terrifying. CIS brought a methodology that gave us confidence. Their 'strangler fig' approach allowed us to modernize piece by piece without a 'big bang' failure. We're now launching new products in weeks, not years." - Jenna Raynor, CTO
Key Challenges:
- Ensuring transactional integrity and ACID compliance in a distributed system.
- Migrating 30 years of customer and transaction data with perfect fidelity.
- Meeting stringent regulatory and security requirements (PCI-DSS, SOC 2).
- Gradually phasing out mainframe functionality without disrupting daily banking operations.
Our Solution:
We implemented the Strangler Fig pattern, building an API layer around the mainframe. New digital services were built as microservices on AWS. We used event sourcing and CDC to keep the new and old systems in sync during the multi-year transition, gradually "strangling" the mainframe until it could be decommissioned.

E-commerce Retailer Boosts Conversion by Migrating from Oracle to Headless Commerce
Industry: Retail & E-commerce | Client: A fast-growing online fashion retailer.
Client Overview: The client's e-commerce platform was built on an old version of Oracle ATG, a monolithic system that was difficult to update. They couldn't easily create new customer experiences for mobile or social commerce, and site performance was poor, hurting conversion rates.
"Our old platform was a bottleneck to growth. CIS helped us move to a modern, headless architecture that gives our marketing team the freedom to innovate. Our page load times have been cut in half, and our conversion rate has seen a significant lift." - Lucas Harrell, Head of E-commerce
Key Challenges:
- Migrating millions of customer profiles and order histories without data loss.
- Integrating with a complex ecosystem of third-party services (PIM, OMS, payment gateways).
- Ensuring a seamless cutover during a low-traffic window to minimize revenue impact.
- Building a new, high-performance front-end on a modern JavaScript framework.
Our Solution:
We re-platformed their backend to a microservices-based commerce platform (commercetools) and built a new front-end using React and Next.js. An API gateway managed all integrations. We performed the final data sync and DNS cutover in a 4-hour overnight window, resulting in zero perceived downtime for customers.

What Our Clients Say
"CIS de-risked what we thought was an impossible project. Their phased approach to our mainframe modernization gave our board the confidence to move forward. The results have exceeded all expectations."
"The depth of knowledge the CIS team brought to our SAP S/4HANA migration was incredible. They weren't just cloud experts; they understood our specific manufacturing processes and challenges inside and out."
"We slashed our Oracle licensing costs by over 70% by migrating to PostgreSQL on AWS. CIS managed the entire process, from planning to cutover, without a single minute of downtime for our critical systems."
"Their AI-powered assessment tools gave us a clear roadmap in weeks, not months. It allowed us to build a solid business case for modernization that our CFO couldn't argue with."
"The post-migration support has been phenomenal. CIS didn't just hand over the keys; they've worked with our team to optimize costs and train them on the new cloud-native tools. It's a true partnership."
"Security and compliance were our biggest fears. CIS built a new environment on Azure that is far more secure and easier to audit than our old on-premise data center. They are experts in regulated industries."
Frequently Asked Questions
We prioritize zero-downtime strategies. Depending on the system, we use techniques like parallel runs (running the old and new systems simultaneously), blue-green deployments (switching traffic instantly to the new environment), and change data capture (CDC) to sync data in real-time. Our goal is for your users and customers to experience a seamless transition.
This is a common challenge. Our assessment phase is critical here. We use automated tools to analyze your custom code and business logic. We then work with your business experts to rationalize these customizations: some are retired (if no longer needed), some are replaced by standard features in the new platform, and the truly essential ones are re-architected as modern, maintainable extensions or microservices.
Data integrity is paramount. We follow a multi-layered approach governed by our ISO 27001 certification. This includes data encryption in transit and at rest, establishing secure connections (VPN/Direct Connect) between environments, and using automated data validation tools that perform row/column counts, checksums, and even cell-level data comparisons to ensure a 100% match between the source and target systems.
This varies greatly depending on the complexity, size, and target architecture. A simple "lift and shift" of a few dozen servers might take 3-6 months. A complex mainframe modernization could be a multi-year program. Our initial Assessment & Roadmap service is designed to answer this question specifically for you. It provides a detailed timeline, resource plan, and cost-benefit analysis, giving you a predictable budget and schedule before you commit to the full migration.
Our goal is not just to match performance, but to exceed it. While legacy systems can be fast for specific tasks, they lack scalability. We conduct rigorous performance engineering, including load and stress testing, to ensure the new cloud architecture is optimized. By leveraging cloud features like auto-scaling, global content delivery networks (CDNs), and in-memory caching, the new system will be significantly more responsive and capable of handling variable loads far more effectively.
Our partnership extends beyond the go-live date. We offer a "hyper-care" period of intensive support immediately following the cutover. After that, we provide a range of services, including 24/7 managed cloud operations, continuous cost optimization (FinOps), security monitoring, and platform engineering. We also work with you to build a roadmap for leveraging your new platform for innovation, such as developing AI/ML capabilities.
