Legacy modernization

Legacy modernization begins with understanding your code. CoreStory accelerates it.

Before you can refactor or rebuild, you need deep visibility and understanding of what your systems actually do. CoreStory uses AI to reverse engineer large codebases into comprehensive technical and business insights in minutes – delivering the understanding you need to modernize with confidence.

Accelerate systems understanding

Teams of seasoned developers take months – even years – to meticulously document and understand strategic applications with millions of lines of code. That is if you can even find the developers and analysts with the necessary skills.

With CoreStory, you can accurately and comprehensively process very large codebases in a matter of minutes, dramatically speeding up your discovery phase and setting your transformation projects up for success from day one.

Comprehensive code intelligence

After CoreStory processes your legacy codebase, it generates an intelligence model containing all the essential code insights required to successfully execute any application modernization project.

The intelligence model includes business requirements, user stories, business rules, workflows, code summaries, dependency maps, architectural insights, and all the essential information from your code.

From COBOL to PHP, we've got you covered

Legacy comes in multiple forms, and you’ll never have enough qualified resources to manually reverse engineer all your legacy code.

With CoreStory, you can document large codebases written in COBOL, C#, C, C++, Java, JavaScript, PHP, PL/SQL, Python, and TypeScript in record time.

Chat with your code

Once your legacy codebase is transformed into an intelligence model, you can query it with a natural language interface to answer questions about your code as they arise.

The intelligence model can also be used to generate key artifacts like business requirements documents (PRDs), and it can be integrated through an API into the tools and processes you already use for key steps in your software development lifecycle.
