Revolutionizing Legacy Systems with Automated Refactoring

In our previous blog, we explored how thorough assessments lay the groundwork for a successful modernization roadmap, pinpointing risks and preventing costly missteps. But what happens after the assessment?

Enter the critical next phase: refactoring; the process of transforming outdated, legacy code into modern, maintainable systems without altering core functionality.

Historically, refactoring meant labor-intensive manual code rewrites. This approach is not only time-consuming and expensive but also prone to human error, often leading to project delays or outright failure. To address these challenges, many organizations turned to semi-automated code conversion tools. While these tools speed up parts of the process, they rarely deliver a complete solution, forcing teams back to manual methods and reintroducing the very risks automation aims to eliminate. For small projects, this might be manageable, but when dealing with millions of lines of code, it’s a recipe for disaster.

mLogica’s LIBER*M Mainframe Modernization Suite redefines refactoring with cutting-edge automation. LIBER*M’s advanced algorithms automatically map and resolve dependencies, eliminating runtime errors and ensuring the refactored application performs as intended. The result is clean, modernized code that aligns with contemporary development practices, including improved structure, standardized naming conventions, and seamless integration with DevOps workflows. This not only simplifies maintenance but also enables scalability in cloud environments.

LIBER*M supports a broad array of legacy languages, such as Assembler, COBOL, Easytrieve, and more, transforming them into modern languages like Java, C#, or updated COBOL versions. For instance, LIBER*M can seamlessly refactor Assembler to COBOL, ensuring compatibility with modern systems while resolving complex dependencies, such as COBOL programs interacting with VSAM files or Assembler routines.

Consider a government organization with over 45,000 employees tasked with modernizing its IBM mainframe batch processing systems running on z/OS. The legacy application portfolio, including COBOL, Pacbase, Assembler, CICS, JCL, Db2, IMS DB, and VSAM, required modernization to align with open system architectures. Enter LIBER*M, which enabled this transition through automated refactoring, accelerating time-to-value while reducing risk and preserving core business logic.

The result?

A seamless transition to a modern, open platform with minimal disruption to users, delivering operational efficiency and significant cost savings.

Relying on outdated legacy systems prevents organizations from evolving and adapting to the future. LIBER*M’s cutting-edge automated refactoring technology delivers a game-changing solution, empowering businesses to modernize with unmatched speed, efficiency, and confidence.

Unlike risky manual rewrites that often lead to failed mainframe conversion projects, LIBER*M ensures success through precise, automated refactoring that dramatically reduces time, costs, and error rates. By accelerating time-to-value, it enables organizations to unlock rapid returns on their modernization investments.

Successful mainframe conversion projects future-proofs enterprises by diminishing reliance on a shrinking pool of mainframe programmers, cultivating versatile, forward-thinking IT teams equipped to tackle emerging challenges. With seamlessly modernized, cloud-integrated code, LIBER*M unleashes unparalleled agility, empowering businesses to innovate boldly, scale effortlessly, and adapt dynamically to market demands.

By minimizing risks, enhancing system performance, and unlocking the full potential of cloud ecosystems, LIBER*M transforms legacy burdens into strategic assets. LIBER*M’s automated refactoring is the catalyst that propels organizations to drive sustained growth and innovation in an ever-accelerating digital landscape.
