Our Services
In today’s fast-paced digital landscape, businesses can’t afford to be held back by outdated technology.
Yet, many organizations still rely on legacy systems that, while stable, may limit their ability to innovate and respond to market demands. That’s where our expertise in Business Rules Extraction and Legacy Modernization makes a difference.
Our approach to Legacy Modernization and Business Rules Extraction is holistic, addressing both the technological and operational facets of your legacy systems.
Legacy Modernization is more than just an upgrade; it is a strategic transformation that re-engineers your applications into modern, efficient systems that can scale with your business. By migrating to platforms like C#, Java, and .NET, we help reduce the risk and cost associated with maintaining outdated technologies while empowering your organization to quickly adopt new features and capabilities.
With our Business Rules Extraction and Legacy Modernization services, you can unlock the value in your legacy systems, reduce operational costs, and position your organization for future growth.
Business Rules Extraction
Legacy systems are built on a foundation of business rules that dictate how they operate, manage data, and support essential business processes. These rules are vital to your operations, yet over time, they often become deeply embedded within the code, making them difficult to access, understand, or modify.
Our Business Rules Extraction services are designed to bring these critical rules to the surface. Using advanced tools and methodologies, we analyze every line of code in your legacy system’s codebase to identify and document the business rules that govern it.
This process not only aids in understanding your current system but also provides a blueprint for future development, ensuring that your business logic is preserved and can be seamlessly integrated into modern platforms.
Data Conversion
Over the past 30+ years, we have worked with just about every kind of data source you can imagine. From legacy structures like C-ISAM, IMAGE, PowerHouse PDL (with its ability to redefine, sub-structure data and add arrays to data structures), RDB, and Interbase, to flat files, CSVs, and hierarchical network databases, chances are, we have seen it, decoded it, and migrated it. At Core, data conversion is not an afterthought. It’s something we have been doing for decades as part of our larger modernization work, and now, we are offering it as a standalone service.
We specialize in converting legacy data into clean, structured formats ready for modern platforms like Oracle, SQL Server, and DB2. Whether your data is locked in an outdated format or spread across fragmented sources, we have the tools and experience to bring it into a coherent, modern structure, safely and accurately.
Legacy Application Modernization
After extracting your business rules, the next step is modernization. While legacy systems are often reliable, they come with high maintenance costs, limited flexibility, and a shrinking talent pool. Modernization isn’t just a tech upgrade—it’s a transformation that makes your operations more agile, efficient, and responsive.
Our Legacy Modernization services follow a systematic methodology that involves your team at each step. We specialize in migrating legacy systems to modern platforms like C#, Java, and .NET, ensuring your applications are future-proof and aligned with industry standards.
Cloud and New Application Development
At Core, building software is something we do every day. It’s not a side skill—it’s part of who we are. Every time we take on a legacy migration, there’s usually a modern application waiting on the other side. That means writing fresh, clean code—often in C# or Java—and making sure it fits seamlessly into today’s cloud environments. Over the years, we’ve developed and delivered full-stack solutions that power real-world operations, not just proof-of-concept demos.
Our teams are hip-deep in .NET and Java. They work with Spring Boot, Spring Batch, MyBatis, and all the moving parts that make enterprise Java tick. On the Microsoft side, we use C#, .NET 8, Dapper, and modern front-end frameworks like React and Angular. These aren’t technologies we dabble in—they’re our daily tools, and we know them well. We also bring in Bootstrap, PowerShell scripting, and work comfortably across Oracle, DB2, and SQL Server environments.
Quality Assurance
At Core, Quality Assurance (QA) isn’t an afterthought, it’s part of how we build. Over the years, we have handled some of the most complex application migrations in North America, and along the way, our approach to QA has evolved into something we are proud to offer on its own. The same deep, hands-on testing methodologies that safeguards our modernization projects powers standalone service to companies that need expert oversight and reliable outcomes.
We work across the full QA spectrum. Our teams design and maintain automated test suites using tools like Playwright to simulate actual user behavior in real browsers. We also build custom scripts to run alongside your application code, making it easier to catch bugs early and release with confidence. If you are doing A/B testing, trying out different layouts, wording, or flows, Core we can help design the test, run it, and make sense of the results.
Project Management
At Core, Project Management is central to everything we do. Over the years, we have led countless system migrations, some spanning thousands of programs and multiple technology stacks.
With that comes a tremendous need for structure, communication, and follow-through. We do not just manage timelines and tasks. We manage expectations, dependencies, risks, and results. In many ways, our ability to keep projects steady and predictable is as important as the migration work itself.
