Liber*M Mainframe Modernization Suite

A more complex methodology, refactoring restructures and optimizes the existing code to improve performance, functionality and overall efficiency of mainframe programs. This approach implements significant modifications to the code base of applications and databases, with the goal of removing technical debt and improving non-functional attributes that restrict agility, cost efficiency and innovation.

Refactoring allows businesses to modernize legacy database environments such as ISAM, VSAM, Db2 and IMS DB to a relational RDBMS environment. We can also refactor legacy mainframe programming technologies such as Easytrieve, Assembler, Telon, PL/I and other 4GLs to COBOL, Java and C# and migrate COBOL to Java, C#, and C++.

In-Depth Experience Lets Us Create Solutions Customized for Your Needs

While many organizations prefer to refactor Assembler code directly to a more modern language such as Java or C#, there are situations in which COBOL is a logical target. These include:

1. Optimizing on the mainframe by consolidating existing languages to COBOL
2. Retaining the ability to leverage in-house COBOL expertise
3. Replatforming mainframe COBOL to a distributed environment, which requires refactoring Assembler to COBOL

Refactoring Assembler to COBOL or Java with mLogica’s LIBER*M automated conversion software suite ensures compatibility with the target system, addresses system dependencies, aligns data representations and improves code maintainability. Inaccurate refactoring can result in migration failures, including runtime errors, incorrect results and difficulties maintaining the migrated system.

Could Your Refactoring Initiative Fail at the Last Mile?

Your legacy system comprises a complex array of databases, applications and languages. While your team focuses on components such as COBOL, CICS, VSAM and Db2 that drive the bulk of your mainframe, it's also critical to address the technologies that support them, including Assembler, Easytrieve, Telon, PL/1 and more.

These technologies, which underpin every critical business function, require comprehensive assessment before modernization can begin, to determine the role each plays in relation to the others and to mainframe function as a whole. This allows you to create an end-to-end modernization strategy. Without a team that is expert in these technologies, your refactoring initiative could stall in the home stretch.

Can You Avoid "The Last Mile Challenge"?

Invariably when our team is brought in to rescue mainframe modernizations and migration projects that are failing in the final stages, we find they have technologies such as Easytrieve, Assembler, Telon, PL/I and other 4GLs in common. Without precision conversion of these critical supporting components, system modernizations are often doomed to disastrous delays or outright failure.

At mlogica, our projects always begin with a comprehensive assessment that documents all technologies and up- and downstream dependencies, so each component of your existing system is fully documented. These components are then placed on a roadmap right at the outset, for expert conversion with no surprises, no logjams—and no delays, just a seamless transition to leading edge technologies that future-proof your business.

Replatforming migrates a business’s mainframe applications and databases to a new runtime environment with minimal changes to the code, while simultaneously ensuring code structures, functions and features remain intact. This allows organizations to offload their mainframe technologies from legacy z/OS, GCOS8 (BULL) and more to an x86-based Linux environment and transform them using new and better toolsets.
