Besides the obvious benefits of faster and more up-to-date development platforms, mainframe modernization can produce a host of additional benefits. These supplemental benefits can impact bottom-line performance, speed to market, employee retention, and overall brand integrity for your organization.
As COBOL experts age out of the workforce, new developers and engineers are no longer developing proficiency in these skills. Upgrading to object-oriented programming languages creates a viable path to cloud integration while establishing consistency with modern IT and development skill sets.
The large footprint, energy consumption, and IT resources required by traditional mainframe architecture present obvious cost concerns combined with unlimited hidden cost potential. A purposeful migration to cloud-based solutions improves efficiency while reducing redundancy and monitoring requirements.
Legacy mainframe architecture is notoriously expensive to maintain, and traditional horizontal scaling (scaling out) produces a linear uptick in maintenance, hardware, and software licensing expenditures. Upgrading legacy code and offloading data to the cloud helps to defray spiraling mainframe maintenance costs.

Successful mainframe modernization projects must focus on determining the strategy, tools, and technologies needed to minimize delays in implementation and risks to business continuity.
Understanding and documenting mainframe resource deployment and assessing the criticality associated with each application are important first steps. A complete inventory and analysis of mainframe components leads to more informed modernization options and roadmaps. An assessment will also uncover underused legacy assets that can be eliminated to trim costs.
Topology mapping provides high levels of insight into the relationships between infrastructure and applications. While many organizations maintain diagrams for specific programs and systems, detailed topology that spans all architectural layers can be useful for developing an optimized modernization strategy.
Integration encompasses the tools and processes that successfully link the mainframe with the larger cloud-enabled ecosystem. Hybrid cloud strategies allow organizations to offload less critical applications, improve visibility, and leverage modern machine learning capabilities.
An assessment can reveal which tech options are the most useful and cost-effective. While a highly functional mainframe with ample capacity might only require code optimization, a mainframe hosting less sensitive or non-redundant applications might benefit from complete re-hosting in the cloud.
A robust planning process involving all key stakeholders is useful for avoiding delays and minimizing unplanned rework. The outputs of this planning should include test and data archiving strategies along with data migration and integration timelines. Detailed planning is one key to avoiding the pitfalls that derail many modernization projects.
Inertia in mainframe modernizations projects is often the result of risk mitigation or a fear of the unknown when it comes to bread-winning mainframe processing, storage, and security functions. Optionality is based on leaving available options open as long as possible. A measured and conservative approach to cloud migration, data retention, and other modernization activities can help to reduce risk exposure and the potential impact of unexpected technical challenges.
A cross-functional commitment to the mainframe modernization project with the input and guidance of industry experts can lead to successful execution with appreciable financial returns. Execution does not end when the modernization effort is completed. KPI and ROI tracking bring greater success and efficiency to the next mainframe modernization effort.
We’ve worked with many different legacy platforms, connecting and modernizing them to state of the art technology and infrastructure.
Integration software used to ‘wrap’ the mainframe system allows any modern system to communicate with them, while still preserving the integrity of and continued operational state of the mainframe.
The rewrite option entails a complete breakdown of the application to determine its minimally viable requirements, followed by a rewrite in a modern language and platform. This may be often the most expensive, and yet, may offer the most value to the organization overall.
This approach involves using software conversion tools to convert legacy code (Natural, Cobol, etc.) into an modern languages to run on modern platforms. Challenges exist using such tools, as they are usually only 80-90% accurate, and require further development to bring closer to 100% pairing with true system requirements.
This rehosting option, ‘lifts and shifts’ all the existing legacy mainframe code to a cloud environment (Azure, AWS, etc.). The application is then accessible with the help of cloud emulators. The underlying business logic and user interface are left intact to minimize project risk and duration. The old code still exists, and updates to it must continue to take place. But at least the hardware issue of the mainframe is addressed.
Senior consultants with previous experience with these types of projects can set the stage for a well-framed engagement.
