Mainframe applications have been the backbone of critical business operations for decades, but as technology evolves, companies are increasingly looking to migrate or modernize their legacy mainframe applications. However, migrating or modernizing mainframe applications is not a simple task, and it requires careful analysis and planning to ensure a smooth transition. In this blog, we’ll explore some of the key considerations for mainframe application analysis during migration or modernization.
Mainframe Application Analysis tools are available from IBM, Modern Systems and Microfocus
From IBM, IBM Application Discovery and Delivery Intelligence for IBM Z (IBM ADDI) is an analytical platform for z/OS or Mainframe Application Modernization that is designed to help developers and architects rapidly discover and analyze relationships between application components, data, and jobs to make changes safely and efficiently.

From Modern Systems, The Enterprise Application Viewer (eav) is a complete analytical team within a single tool. eav provides both application and business teams with the ability to quickly understand and follow the logic within applications, between applications and within programs – meaning you’ll no longer need technical specialists for each application. A core team of programmers and analysts can debug, maintain, and enhance multiple complex applications within any environment using eav.

We can do initial assessment with client’s application sizing, complexity and choice with comparison and decide the tooling for analysis.
Application inventory
Before migrating or modernizing mainframe applications, it’s essential to understand the scope of the project. A complete inventory of all the applications running on the mainframe is necessary to identify which applications are critical to business operations and which can be retired or replaced. This inventory will help prioritize the applications that need to be migrated or modernized first and ensure that all applications are accounted for during the process.
Application dependency analysis
Mainframe applications often have complex interdependencies with other applications, databases, and systems. It’s important to analyze these dependencies to understand the impact of migrating or modernizing one application on others. This analysis will help identify any potential issues that could arise during the migration or modernization process and allow for appropriate mitigation measures to be put in place.
Application functionality analysis
One of the most important aspects of mainframe application analysis is understanding the functionality of each application. This analysis involves reviewing the application code, identifying the business rules and logic, and determining how the application interacts with other systems. This analysis will help identify any areas that may need modification during the migration or modernization process and ensure that the application continues to function as intended after the transition.
Application performance analysis
Mainframe applications are often designed to handle large volumes of data and transactions, and their performance is critical to business operations. It’s important to analyze the performance of each application to identify any bottlenecks or areas that need improvement. This analysis will help ensure that the application continues to perform well after the migration or modernization process.
Application security analysis
Mainframe applications often contain sensitive data, and their security is crucial to business operations. It’s essential to analyze the security of each application to identify any potential vulnerabilities and ensure that the application meets the security requirements of the organization. This analysis will help ensure that the application remains secure after the migration or modernization process.
The above are few common Analyser tool functions, we will be providing Blog on Specific tool that would help to understand the unique feature of each tool.
Conclusion
Mainframe application analysis is a critical aspect of any migration or modernization project. It requires a thorough understanding of the applications, their functionality, dependencies, performance, and security. By conducting a comprehensive analysis, organizations can ensure a smooth transition and mitigate any potential issues that may arise during the process.
As technology continues to evolve, mainframe application analysis will remain a crucial part of IT strategy for organizations that rely on legacy mainframe applications.
