How much automation actually makes a difference?
10% of 10 million lines of code is still 1 million lines.
A major modernization project involving millions or tens of millions of lines of code can take years and cost millions of dollars. Using artificial intelligence and modern computing method and automation, much of that time and expense can be eliminated. The question is, by how much? If your project starts out at 10 million lines of code and your automation technique cuts that down by 90%, you’re still left with a 1-million-line project that can take months to manually assess, document, transform, and refactor.
To appreciably accelerate large modernization projects, automation must eliminate as near as possible to 100% of the effort. That means in the range of 99.9X%. Without that, your organization can be left with significant and costly manual loads that can take years, strain budgets, result in unacceptable error rates, and still produce poorly written modern code. Even advanced automation cannot take code straight from any source language to a modern cloud-ready language. First, the code must be translated through a universally accepted language modeling system and standard to maximize the extensibility and efficiency of application analysis, transformation, and refactoring—an Intermediate Object Model (IOM). This is one of the keys to accelerating modernization that The Software Revolution Inc. (TSRI) has implemented for their clients.
The languages used for specifying grammars and transformations must fit the specific problems at hand and be as expressive and efficient as possible. TSRI has developed and defined three domain-specific high-level specification languages JPGEN™, JTGEN™ and JRGEN™:
JPGEN™ defines grammar system and language models
JTGEN™ delineates transformations between these models
JRGEN™, a 5th generation artificial intelligence language supports first order logic and predicate calculus as well as 3GL and 4GL language constructs
Together, these three proprietary tools comprise TSRI’s JANUS Studio®.
IOM: A Literally Exponential Improvement in Transformation
The three components of JANUS Studio® transform and compile software code originally developed in language such as Ada, Visual Basic, Vax Basic, C, C++, COBOL, C#, Java, Jovial, FORTRAN, and more than 30 other languages into efficient, platform-neutral C++. The core function of the IOM creates a language-neutral model into which all legacy source languages are transformed, and from which all modernized target languages can be generated. The IOM is effectively a universal translator. It simplifies the “O(n-squared)” language transformation problem to a much simpler “O(n+1)” language transformation problem. The IOM provides a set of generic language constructs that serve as a reusable language-neutral formalism for assessment, documentation, transformation, refactoring, and web-enablement.
This solution allows simple 64-bit multi-processor LINUX platforms to analyze massive software models using parallel processing.
Using IOM, and the expertise of TSRI’s exceptionally skilled developers, JANUS Studio® is simply the most powerful, least expensive, and lowest risk technology available to automatically modernize (assess, document, transform, refactor, and web-enable) legacy systems. Using the AI-enhanced capabilities of JANUS Studio®, 99.9X% of software transformation can be automated, cutting transformation project times from years to months—or weeks.
"Simply the most powerful, least expensive and lowest risk technology available to automatically assess, document, transform, refactor, and web-enable legacy systems.”
A Model for Automated Modernization
As Scale Increases, So Does Efficiency
JANUS Studio® allows TSRI developers to cut modernization projects so drastically using Artificial Intelligence-based modeling that drives that 99.9X% automation rate. Not only that, but because every application and every language is modernized and transformed at the meta-model stage, every prior project (regardless of the language or industry) further develops the toolset and TSRI libraries, resulting in greater value for each future project. The more scale, the more uses, the more efficient the process.

Only a few engineers know how it feels to lead a major government agency through an automated mainframe modernization for multiple applications from COBOL to Java on the Microsoft Azure cloud. TSRI’s Executive Vice President of Engineering & Service Delivery, Roger Knapp, is one of them!
Get the story straight from Roger in his interview with GovCIO about his experiences modernizing multiple applications for the U.S. Department of Housing and Urban Development (HUD).
Also, be sure to check out TSRI’s case study to learn more about our work with GovCIO to transform multiple Mainframe Unisys 2200 COBOL with DMS2200 databases to Java with a factory-style process. The modernized systems were deployed on the Microsoft Azure Cloud and hook directly into the Microsoft Azure DevOps pipeline!
TSRI utilized the same proven JANUS Studio® modernization solution, process, and approach we have leveraged for our other IBM, Tandem, Unisys, and other mainframe modernizations. During the project, TSRI provided “As-Is” and “To-Be” application documentation. We utilized our powerful refactoring engine to improve code quality, maintainability, readability, and security to meet the HUD’s needs. HUD’s modernized applications (CHUMS, F42d/CAIVRS, and LOCCS) are live, in production, and being actively maintained by Java developers.
This program was also the first-ever modernization utilizing the U.S. Technology Modernization Fund (TMF) distributed by the General Services Administration (GSA) and hailed as a resounding success! Maria Roat, the deputy federal chief information officer, shared in a CompTIA webinar that the U.S. government’s technology modernization fund (TMF) is about accelerating projects and enabling multi-year funding.
“HUD mainframe modernization, there’s a playbook coming out of that. So other agencies, they’re going through their mainframe modernization, they can take lessons learned from HUD and apply that,” she said. “As we as we look to scale and accelerate the board, there’s a lot of things that we’ve already done over the last three years, as we’ve matured, that we can apply to the future funding.”
TMF allowed HUD to move off the mainframe completely, get OPEX savings and achieve an amazing reduction in TCO for the Department (80%+ compared to the mainframe TCO).

As we enter a new year, it’s only natural to look back on what we accomplished in the past 365 days. Many of those accomplishments centered around explaining what TSRI does in a way that nearly everyone can understand. Software modernization and refactoring solutions are, by their very nature, complex concepts. Teams of specialized engineers are required to successfully complete each project, and even the simplest automated transformations can take months to get all the right pieces put into place.
In this blog, we highlight some of the most informative pieces published in 2021. These materials were designed to help make the automated modernization process easier to understand and navigate from start to finish. We hope you’ll find them useful as you consider your organization’s IT plans and modernization initiatives for the coming year.
GETTING READY TO MODERNIZE!
Modernizing to the Cloud
Scott Pickett, TSRI’s Vice President of Product Operations and Service Delivery, conducted a live presentation that discussed how automated modernization can help organizations move their applications to the cloud. The presentation resulted in a complete series of videos, all of which are accessible from the post linked above.
Check out this article featuring a downloadable Checklist: Preparing for Cloud Modernization to help you assess your organization’s current assets, including your existing codebase, databases, and other tools that may be installed on your mainframes and other legacy technologies.
MODERNIZE WITH LESS DISRUPTION
One of the major risks of any modernization is the amount of time a system will be taken offline during cutover to the new environment. Any downtime becomes a disruption to the business, whether that means lost revenue or maintaining security of mission-critical systems. This post, 4 Tips for Modernizing with Minimal Business Disruption discusses ways that organizations can mitigate disruption, and also explains how proofs of concepts, step-wise automated migrations, and proper planning play into maintaining continuous uptime.
Common Misconceptions About Modernization (And What to Do About Them)
Application modernization is a game changer in any organization. Oftentimes, perceived obstacles, such as prolonged system downtime, get in the way of bringing mission-critical applications to modern programming environments. This article helps to dispel many of those notions.
Automated Refactoring: The Critical Component to Achieving a Successful Modernization
When any application gets modernized, the codebase shifts from a legacy language such as COBOL or PL/1 to a modern language such as C# or Java. However, just because the language is up to date doesn’t mean the system will operate more efficiently. That’s why refactoring is so important: this automated, iterative process eliminates dead code and redundancies while streamlining the entire application. It’s truly the key to more secure, robust applications.
Microservices Offer Robustness and Security in Modern Systems
Many, if not most of the clients who modernize their mainframes with TSRI started out with monolithic systems. All functions in the workflow relied upon one another, and if one area went down, the entire system went down. Modern software architecture operates using multiple tiers that interoperate with one another, but aren’t dependent on each other. That means if one area goes down, the entire system doesn’t go down with it. A component of this structure, known as microservices, makes for easier software maintenance and also protects organizations while allowing for faster go-to-market strategies for new applications.
Cloud Migration and Containerization: 3 Steps to Reduce Risk and Ensure Success
An important benefit to automated modernization is how the business logic of the transformed application never changes. Sometimes, particularly when modernizing to the cloud, the legacy application may still require some usage. Rather than keep the mainframe in operation or employing some other inefficient, insecure method, transforming to a containerized modern codebase can keep those application instances separate from the rest of its processes. This method increases security and efficiency while allowing for further system development in modern languages.
As you contemplate modernizing your mainframe or embedded-system applications in the new year, we hope these articles will provide you with the knowledge you need to move forward.

No change in business logic.
Reduction in overhead costs.
Continuous development during and after migration.
These are a few modernization concepts that Scott Pickett, TSRI’s Vice President of Product Operations and Service Delivery, discussed on his recent appearance on Amazon Web Services’ APN TV channel.
“TSRI allows for an ability to do automated transformation of not only your language, but your application to the cloud environment, allowing you to bring in skilled, modern technology to your legacy implementations, being able to drive down the cost point associated with ongoing operational costs, and being able to deliver new applications, new functionality, new screens, and new capabilities in that modern language,” he said in his talk.
So what does that mean, exactly?
In TSRI’s modernization of a major European bank to the cloud, that meant they modernized approximately 80,000 lines of code at 99.7% automation. In other words, only 384 of those lines of code were hand-written. That's big for a project of this size—but it's huge when you're talking about applications with hundreds of thousands or even millions of lines of code!
For any organization, whether in commercial enterprise organizations like the banking client mentioned above, or in government agencies, modernization reduces risk.
“You're able to bring a new skill set, new experts that know Java and know CI and CD tools and apply them to your legacy application that's been modernized,” Scott said. “It literally also allows for the ability to drop tens of thousands, and even hundreds of thousands of dollars, off your monthly costs.”
As Scott also noted in his presentation, “we can not only transform code quickly…because there are very, very few manual changes, but it also means that you can migrate to the cloud and then be able to not have any business logic change associated with that migration.”
Maintaining business logic is a big deal when it comes to systems that measure their age in decades rather than years and the original programmers have long since moved on.
One other interesting point Scott brought up is how TSRI’s tools have enabled customers to maintain agility and competitive advantage by providing its clients with the modern, cloud-based applications they need—all while reaching back to its legacy DB2 database that supports the applications that have yet to be modernized.
Throughout the talk, Scott also pointed to how TSRI has adopted a step-wise model, which modernizes small applications or pieces of an application, tests for validity, then pushes into production before the next applications are transformed. Such a methodology allows the client to continue to develop in the legacy language, maintain a common data set, and minimizes business disruption to almost zero.
“There’s no big delay. You can continue developing the legacy and we can migrate those legacy applications while the transformations are happening and migrate them into your modern environment,” he said.
Scott also explains the steps of an automated migration in layman’s terms and how a TSRI transformation integrates cleanly into cloud services like AWS using containerization and microservices.
We of course don’t want to spoil the presentation by giving everything away, so head over to APN TV and watch for yourself to learn about how automated modernization to the cloud will save your organization time, money, and the headaches from continuing to maintain legacy systems.

Modernization’s hot.
If there’s a single takeaway from TSRI’s experience as a sponsor and exhibitor at AWS re:Invent 2021 in Las Vegas, it’s that enterprises and governments alike have their minds on software modernization. If they haven’t started the process of migrating their mainframes and legacy applications to modern architectures to the cloud, then they will be soon actively moving in that direction.
“Virtually every CIO who has a mainframe application is now looking to migrate,” said Scott Pickett, TSRI’s Vice President of Service Operations and Product Delivery, who attended the conference at the end of November.
“Mainframe modernization was the centerpiece of activity for the conference-goers we interfaced with at AWS re:Invent,” echoed Greg Tadlock, TSRI’s Vice President of Sales. While modernization comes in many different flavors—mainframes can be transformed in multiple ways (replatforming, redevelopment, or refactoring, for example.), software modernization is a niche inside the modernization industry. It’s a niche that TSRI has embraced for over two decades and doubled down on earlier this year through validation and selection as a launch partner of the AWS Mainframe Modernization competency. Mainframe application modernization is clearly a movement that has entered the mainstream. “The validation that we made the right decision to be a launch partner with AWS on their Mainframe Modernization competency was confirmed at the re:Invent conference,” Tadlock said.
As a company, TSRI has mainly focused on migrating legacy systems to modern languages and architectures, whether on-premises or on the cloud. One thing that surprised the on-site team at re:Invent were the questions about round-tripping. In essence, a round trip is a refactoring of applications originally written in software languages that most modernizations currently target, Java or C#. Both languages have been in use for two decades (or more) themselves, and the technology landscape has changed significantly during that time.
“They came to us specifically because they saw refactoring and the need to take their older Java or C# apps and get them refactored to targeted cloud services, microservices, and containers,” said Kory Caze, TSRI’s Lead Account Executive. It’s a service TSRI has begun to offer, and will certainly become a focus area in the coming year.
The refactoring or transformation of nearly any legacy language to modern languages is certainly one the core values TSRI offers to the modernization market. The capability to modernize more than standard IBM COBOL applications can be useful for, say, an airline that needs to modernize their FORTRAN applications—an opportunity that actually presented itself at the conference this year.
“There are so many software languages and technologies out there, that you can't have a one-size-fits-all solution for,” Kory said. In fact, TSRI’s Director of Business Development, René Wagner, had three different inquiries about doing a transformation from MUMPS, a relatively obscure mainframe language originally developed for healthcare operations—all within 10 minutes of each other! “It's like the most random language,” said René.
Knowing that several companies have joined AWS’s Mainframe Modernization competency is reassuring to smaller companies like TSRI. They have a significant role to play in bringing major corporations and public sector agencies to the cloud quickly and efficiently, according to René.
“If you went over to the modernization area [at re:Invent] and you asked Amazon, ‘Who do you use to transform your systems to modernize the mainframe?’” René said, “their answer was, ‘Oh, we have an ecosystem of partners that we utilize to get this work done.’”
Everyone on the TSRI team saw live, in action, that modernization will be important over the next few years. Migration to the cloud, they all said, is not a matter of if, but when.
“That was kind of the feeling that I got,” René said. “Modernization is happening, and these people have bled enough on what they currently have.”
While TSRI has begun to focus more of its efforts on cloud migrations, with AWS as a leading platform, the re:Invent conference opened the company’s eyes to plenty of opportunities that the company’s leadership might not have considered even a year or two ago. Being on the floor as a first-time sponsor and having the ability to demonstrate what the company can do, through Application Blueprint® demonstrations, or walking booth visitors through case studies, has opened a lot of doors for the TSRI team.
“The AWS mainframe migration announcement validates the tools, capabilities, and shift that TSRI has undergone, as well as in the industry,” said Scott Pickett, TSRI’s Vice President of Service Operations and Product Delivery.
Next year should be even more interesting.

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:
What are the Challenges?
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.
