Common Misconceptions About Modernization (And What to Do About Them)
Downtime, lack of agility, and vendor lock may keep organizations from modernizing their aging legacy applications, but plenty of other roadblocks, whether technical or psychological, can also stand in the way from an organization from undertaking a high-stakes modernization effort. For example:
- One TSRI defense client had been using the same COBOL mainframe applications for nearly 50 years. The agency expected that migrating away from this mission-critical system would require downtime that could have led to data loss, mission interruptions, and catastrophic security failures.
- Another client, a large European bank, used mainframe applications that could have served them well for another decade or longer. However, upstart digital competitors were running circles around this financial powerhouse. They needed more agility.
- Another defense client wanted to migrate its applications to Amazon Web Services but worried about limited options. Their mainframe used a proprietary architecture and applications, and the agency was locked into long-term contracts that would have prevented them from undergoing a transformation. This agency needed assurances a transformation could be done—and done properly.
Understanding and Overcoming the Misconceptions and Fears
If you’re a change maker in your organization — whether on the business or IT side — you probably see the need to modernize your applications. Throughout our 26 years of modernizing critical applications, we have found that many perceived obstacles are actually misconceptions, fears, uncertainties, or doubts that arise due to a lack of information.
Here are the most common misconceptions and obstacles, and how we help our clients get around them:
Obstacle 1: “It Will Cost Too Much!”
Cost almost always rises to the top of the list. From an OpEx perspective, once a modernized system goes into production, your organization can achieve savings quickly and dramatically. One client reduced its IT operations costs from over $1 million to tens of thousands of dollars—per month. While not every transformation will yield remarkable savings like that, your organization will recoup its modernization costs quickly.
In addition, because an automated transformation is much less likely to produce the inevitable errors produced by humans—we are, after all, only human—that means far lower instances of cost overruns.
Obstacle 2: System Downtime
Many organizations see time to market and system downtime as major concerns. Undertaking an automated modernization will be the fastest, most reliable alternative nearly all the time. As opposed to rewriting all or most of the code in the target language by hand, a fully automated transformation can take months—if not years—off the timeframe to bring the modernized application into production. Such automated modernizations also can give you the option to run your applications in the legacy and modernized environments side by side for testing, and then flip the switch to put the new environment into production with very little, if any, downtime—which means no disruption to the business.
Obstacle 3: “If it Ain’t Broke, Don’t Fix it!”
Organizations may also face the dilemma of making change if there isn’t a need to change. Such attitudes can be embedded into an organization’s culture, and convincing top management to commit to large expenditures where much of the beauty lies under the hood can be a heavy lift. However, external issues may force a modernization—oftentimes when it’s too late.
Most enterprise companies and government agencies running mainframes historically had armies of programmers that maintained their systems. As the decades rolled by, however, most of those programmers retired from the workforce while computer science programs shifted to educating on modern, object-oriented languages like C# or Java. As one client discovered for PL/1, a much more obscure mainframe language, the agency that ran the application found only a single person in the entire country capable of supporting the application. That was clearly not a sustainable solution.
Even more challenging, the language or platform itself may have survived past its reasonable lifespan. TSRI has modernized applications originally housed on mainframes built by Wang. The company ceased to exist in the 1990s and its subsequent iterations no longer supported a version of COBOL proprietary to its systems. At that point, modernization wasn’t a luxury—it was a necessity.
Obstacle 4: The Knowledge Gap
Finally, when a legacy system has been in service for 40, 50, or even 60 years, the original developers will doubtfully still be a part of the organization. Institutional knowledge can be passed down, but most IT leaders won’t have a clear view of what their systems can do. The transformation engine that takes on an automated modernization can also generate documentation that provides a detailed blueprint of an application today and how it will function in the modern target language. Those insights will help the engineers who maintain the application understand how a modernization can achieve their business goals.
Face the Fear and Reap Big Rewards!
Undertaking a drastic change like modernizing an application comes with risks and likely some trepidation, but it also creates opportunities that might never have been possible by continuing to maintain a legacy system. Completion of a successful transformation will not only save your organization money and give you better access to development resources, it will make your organization more agile and provide you with modern tools to better serve your end users.

Video: Effective Testing During Modernizations
When you use automation to modernize applications that you’ve been running for years, there should be no functional change between the legacy code you’ve migrated from and the target language you’ve transformed to. That dramatically simplifies testing.
As Scott Pickett explains in the latest episode of our “Migrating Your Mainframe to the Cloud” video series, you can create quick test scripts to confirm that the business logic has stayed exactly the same. From there, knowing that the automated modernization has created that like-for-like codebase in the new target language means that you simply need to confirm that the data baselines you set are in sync and you’re off to the races!
As Scott does note, TSRI’s solution does inject telemetry into the modernization so you will have logs to help with those code and data comparisons, which makes the full testing process that much simpler.

Video: Modernizing Using Layered Architectures
One huge benefit to an automated modernization is the migration from a monolithic architecture to a multi-tier architecture. The multi-tier, or layered, architecture separates the data layer from the logic layer, and also makes the presentation layer—what the end user sees and interacts with—independent of the other two. In this video segment, Scott Pickett discusses how this modern-day style of architecture allows developers to extend the functionality of an application without affecting the data or behavior of an application. Even more important, however, he explains how a modernized application can continue to refer back to legacy databases when organizations migrate to their target environment in smaller steps rather than committing all at once.

Video: Using Automation to Quickly and Accurately Move to a Multi-Tier Environment
As Scott notes in this video, the latest in our Modernizing for the Future series for undertaking a cloud modernization, “One of the benefits associated with using an automated technology is that none of it is done by hand.” In this video Scott introduces the idea of automation when it comes to modernization and how taking this avenue will preserve the functionality and logic of the legacy applications. The benefit is that the application will operate exactly the same way it did previously, but with capabilities to expand into a more tiered approach so the application can take advantage of the best the cloud has to offer.
Originally aired live on May 18, 2021.
Additionally, having the automated transformation preserve the functionality means once organizations are ready to put the cloud applications into production, the data layer remains consistent so this can be done gradually with very little downtime in the production environments. That minimal business disruption greatly reduces the risk of data loss and technical failures. And from there, automated and semi-automated refactoring can begin to improve the quality and functionality of the application—all in a cloud environment.

Automated Refactoring: The Critical Component to Achieving a Successful Modernization
Using automation to modernize mainframe applications will bring a codebase to today’s common coding standards and architectures. But in many cases, modernization to an application’s functional equivalent isn’t always enough. Organizations can do more to make their modern code more efficient and readable. By building refactoring phases into their modernization projects, organizations can eliminate the Pandora’s box of dead or non-functional code that many developers don’t want to open, especially if it contains elements that just don’t work.
Using TSRI’s automated refactoring engine, remediation was complete in an hour.
What is Refactoring and How is it Used?
Refactoring, by definition, is an iterative process that automatically identifies and remediates pattern-based issues throughout a modernized application’s codebase. For example, unreferenced variables or unnecessary redundant snippets could exist throughout the application. This scan, known as dead/redundant code refactoring, will find repetitions of any of this unusable code to flag, then remove it from the codebase. One of TSRI’s current projects found 25,000 instances of a similar issue that would have required 15 minutes of manual remediation per instance—not including the inevitable introduction of human error that would require further remediation. The number of development hours would take more than a year for a single developer to complete.
Using TSRI’s automated refactoring engine, however, remediation was complete in an hour.
Calling refactoring its own post-modernization phase is, in some ways, misleading. Refactoring typically occurs all the way through an automated mainframe transformation. As an example, in a typical COBOL or PL/1 mainframe modernization, TSRI would refactor the code from a monolithic application to a multi-tier application, with Java or C# handling back-end logic, a relational database layer through a Database Access Object (DAO) layer, and the user interface (screens) modernized in a web-based format. Believe it or not, many legacy applications still run on 3270 green-screens or other terminals, like in the graphic below.
Once the automated modernization of the legacy application is complete, the application has become a functionally equivalent, like-for-like system. However, any deprecated code, functions that may have never worked as planned, or routines that were written but never implemented will still exist. A process written in perhaps 1981—or even 1961—may have taken far more code to execute than a simple microservice could handle today.
Situations like this are where refactoring becomes indispensable.
Where to begin?
Before a formal refactoring process can begin, it’s important to understand your goals and objectives, such as performance, quality, cybersecurity, and maintainability. This will typically mean multiple workshops to define which areas of the modernized codebase need attention and the best candidates for refactoring, based upon the defined goals. These refactorings will either be semi-automated (fully automated with some human input) or custom written (based upon feedback from code scanners or subject-matter experts.)
The refactoring workshops can reveal many different candidates for refactoring:
- Maintainability: By removing or remediating bugs, dead or orphaned code, or any other anomalies the codebase can be reduced by as much as one third while pointing developers in the direction of any bugs in need of remediation.
- Readability: Renaming obscure functions or variables for a modern developer to fit within naming conventions that are both understandable and within the context of the code’s functionality.
- Security: Third-party tools such as Fortify and CAST can be utilized to find vulnerabilities, but once found they need to be remediated through creation of refactoring rules.
- Performance: Adding reusable microservices or RESTful endpoints to connect to other applications in the cloud can greatly improve the efficiency of the application, as can functionality that enables multiple services to run in parallel rather than sequentially.
What are the Challenges?
- Challenge 1: One reason refactoring must be an iterative process is that some functionality can change with each pass. Occasionally, those changes will introduce bugs to the application. However, each automated iteration will go though regression testing, then refactored again to remediate those bugs prior to the application returning to a production environment.
- Challenge 2: The legacy architecture itself may pose challenges. On a mainframe, if a COBOL application needs to access data, it will call on the entire database and cycle through until it finds the records it needs. Within a mainframe architecture this can be done quickly. But if a cloud-based application needs to call a single data record out of millions or billions from halfway across the world (on cloud servers), the round trip of checking each record becomes far less efficient—and, in turn, slower. By refactoring the database, the calls can go directly to the relevant records and ignore everything else that exists in the database.
- Challenge 3: Not every modernization and refactoring exercise meets an organization’s quality requirements. For example, the codebase for a platform that runs military defense systems is not just complex, it’s mission critical. Armed forces will set a minimum quality standard that any transformation must meet. Oftentimes these standards can only be achieved through refactoring. A third-party tool like SonarQube in conjunction with an automated toolset like TSRI’s JANUS Studio® can be utilized to discover and point to solutions for refactoring to reach and exceed the required quality gate.
In conclusion, while an automated modernization will quickly and accurately transform legacy mainframe applications to a modern, functionally equivalent, cloud-based or hybrid architecture, refactoring will make the application durable and reliable into the future.

4 Tips for Modernizing with Minimal Business Disruption
Let’s face it. Change is hard. Sometimes, however, change is necessary. When it comes to modernizing mainframe systems that have been in service for decades — especially when considering the possible risks — change requires a lot of forethought.
Disruption to your organization’s business will likely be one of the biggest risk areas in question. These risks can run from prolonged periods that take your business offline to database synchronization between your existing and target applications. So how do organizations move forward with a much-needed modernization to the cloud or a hybrid on-premises solution without causing major disruptions or headaches to their business?
Here are four tips to help you minimize business disruption risks:
1. Understand the scope of your modernization project.
Your organization may want to modernize your applications all at once, but more likely will consider a proof of concept. Great candidates for a proof of concept could be applications most critically in need of modernization, or less-utilized applications to demonstrate how a cloud or on-premises hybrid migration will holistically affect your overall systems portfolio. Understanding the application make-up and baselines of your existing applications will help uncover any additional services that may be required for a successful modernization and determine the target environment these applications will live on and language they use. Setting a realistic scope early on will give insight into which cloud services your applications can leverage, and the benefits associated with those services. Having a good understanding of the scope of the modernization before the work begins will eliminate surprises down the road as well and help prepare for subsequent steps in your organization’s modernization journey.
2. Consider a graceful migration and gradual roll-out.
With the right solution, your organization has the capability to migrate legacy systems one feature, one function, or even one API at a time. Both the existing and modernized applications can then coexist and run concurrently while maintaining or replicating the same data sources. One TSRI client actually operated in this state for over a year as we completed their modernization!
3. Put your services in the target environment under the control of your legacy environment.
Rather than remaking all of the thousands of processes that run to complete specific tasks, organizations can work on the new target environment following a code migration and create a “cloud agent” to enable the legacy mainframe system to run these processes. This temporary fix mitigates risk by eliminating the challenge of isolating problems in real time and allows organizations to move the processes from the legacy application.
4. Take advantage of automation.
Automated modernization processes eliminate the need for humans to rewrite tens (if not hundreds) of thousands of lines of code, which will inevitably introduce errors that need to be isolated and remediated. Manual rewrites can also take years. While human intervention is likely required at various points in an automated modernization, a programmer will need to touch less than .05% of a codebase, meaning issues can be remediated in hours or a few days rather than weeks. Read more about the advantages of automated modernization.
While any modernization will cause some level of disruption, a trusted partner with the experience, tools, and methods in place to migrate legacy systems will minimize risk and make your move to the cloud or a hybrid on-premises architecture as seamless as possible. An experienced, knowledgeable partner will also keep your business requirements top of mind. Remember, automated modernization and refactoring processes will update your code but do not change your business functions. Everything in your applications will perform exactly as they did prior to your modernization—and most likely better— and also enable your organization to leverage the benefits of cloud computing and the up-to-date processes modern systems offer.
