PWC, Microsoft and Asysco announce legacy transformation partnership

April 25, 2022

On April 20th, PWC, Microsoft, and Asysco announced a partnership to accelerate legacy transformation into the cloud.

In a world, in which innovations happen faster than ever, enterprises recognize the need to modernize their infrastructure. Digital transformation is on the top of the modernization agenda of most CEO’s and CIO’s. Moving to the cloud is an essential component. Many organizations still depend on mainframe systems for their business-critical applications and processes which, in many cases are self-developed.

PWC’s The Mainframe to Cloud transformation approach ensures that organizations can safely and reliably transform their IT systems to customer-centric, agile, and scalable cloud-based platforms in order to accelerate time-to-market and service provisioning.


The success of a Mainframe to Cloud transformation is largely determined by the adaptability of the customer’s organization, their knowledge of the complex technical systems, and management buy-in. This partnership between PWC, Asysco, and Microsoft is therefore specifically aimed at the transformation of people, processes, and technology, from strategy all the way to execution.

This unique approach is therefore more than ‘just’ an IT transformation. It is aimed at finding the right balance recalibrating the transformation strategy, the impact on financial and operational management, and ensuring active contribution from the entire organization. By applying change management on every level, financial, operational, security, and HR, this partnership is the first true solution for large-scale mainframe transformation.

The qualities and experiences of PwC, Asysco and Microsoft are essential. PwC provides market knowledge and transformation expertise for Mainframe to Cloud. Asysco provides fully automated, safe, and proven technology for the transition from mainframe to Cloud. Microsoft Azure is the hyper-scale cloud platform serving as the landing zone simultaneously providing the possibilities for further development and innovation, application modernization, and data insights.


New comparative study: Proven benefits from legacy code conversion

April 6, 2022

– 7N Advisory’s view on the practical implications of legacy code conversion

Large IT organizations often deal with legacy applications. Maintaining these can be challenging. Specifically, resource availability, keeping up with the pace of change, and the need for improved functionality, and flexibility at lower costs. Asysco AMT conversion engine aims to tackle this problem by converting mainframe legacy source code to modern platforms and technologies (Java or C#). This creates new possibilities for modernization.

CAST and Asysco agreed to objectively study and compare overall application quality metrics for a representative, end-to-end mainframe migration. The study compares the quality and risks, of a Policy Admin System before and after the conversion. Converting and moving 2 million lines of code from the IBM Mainframe environment to a Microsoft .NET cloud environment.

The results show a massive quality improvement in the converted code, at the expense of an acceptable and maintainable increase in lines of code among a variety of additional benefits.

This means for organizations that legacy code conversion is a valid alternative that should be taken seriously by those wanting to move away from mainframe setups.

Independent study confirms Asysco’s AMT migration greatly improves overall mainframe system quality

March 28, 2022

By Herman Eggink, COO, Asysco

CAST software recently conducted an independent assessment of a mainframe migration for the Ingenium Policy Admin System for an insurance company in the US. In this assessment, ISO metrics were compared for the entire mainframe system, using technologies such as COBOL, CICS, Easytrieve, JCL, DB2, FTP running under IBM z/OS, with the migrated environment, using only native Microsoft technologies such as .NET, C#, SQL Server, Azure DevOps, IIS running on x86 under Microsoft Windows.

In all key areas, such as Security, Reliability, Performance Efficiency, Maintainability, Robustness, Security, and Changeability, metrics improved significantly.

IBM Mainframe environment:

 Converted AMT .NET environment:


The full report is available here.

The assessment was done using CAST “Imaging” based on a deep dive syntactic and semantic parsing of all application layers. The assessment model proposed by the CAST platform was a concrete implementation of the ISO-5055 norms, targeting the structural quality as defined by the CISQ ( The abstraction level allows comparing the same software characteristics from different technologies, hence evaluating structural quality the same way for both mainframe and .Net technologies. These measurements are not only useful to assess and scope our code conversion projects but also enable us to sanitize the source code, pre or post-conversion.

The assessment was also evaluated by 7N, a leading data-driven digital advisory specialized in solving complex IT challenges. “The result of the study shows that legacy code conversion is a valid alternative that should be taken seriously by those wanting to move away from mainframe setups,” says Freek Hoekstra, Management Consultant at 7N.

This independent study and evaluation underlines Asysco’s AMT conversion technology leadership and proves that systems migrated by Asysco are a great starting position for further modernization.

Our mainframe modernization approach allows moving fluidly from re-hosting through refactoring to total transformation. Asysco’s ‘as is code conversion’ approach converts COBOL into modern language without additional emulation software that offers enterprises the choice to retire the COBOL or continue to use it.

CAST Imaging reverse engineers and automatically ‘understands’ software systems built with any mix of 3GL, 4GL, Mobile, Web, Middleware, Framework, Database, Mainframe technologies. It creates accurate, zoomable architecture blueprints of all database structures, code components, and their interdependencies that allow faster decoupling, refactoring, and re-architecting.

CAST Software also provides CAST Highlight along with CAST Imaging. These “MRI for software” can be used to define either the pre-migration modernization roadmap, in case of a large mainframe environment that requires a phased, incremental approach, or a post-migration modernization roadmap, in case of big bang migrations to the cloud.

We also worked with Erik van Enk, Microsoft Global Black Belt Mainframe Modernization on this project. In his words, “Mainframe transformation isn’t easy. So, why is it so hard? In theory, mainframe applications look like a multilayer environment. But they look like a sort of spaghetti when you do a proper assessment. This approach will help, and guide getting real insights into the mainframe environment and supports creating the right strategy about how we can transform the mainframe applications to Azure in a controlled and secure way. Knowing all the relations and interdependencies between applications, databases and APIs is key to build a roadmap to transform to Azure”.

Erik says, “another important element is maintainability of the migrated code after the transformation. Any mainframe user still doubting the power and validity of this approach can now comfortably do a pre and post-assessment. I am confident that they will get at least the same results”.

Fujitsu in partnership with Asysco, migrated SPV in one seamless move

January 20, 2022

Seamless migration amid a global pandemic

Anticipating future synergism with sister agencies, Sweden’s National Pensions Board (SPV) contracted Fujitsu, in partnership with Asysco, to migrate and modernize its platform in one seamless, efficient move.

The one-to-one migration meant legal agreements and functionality for members remained intact. Despite disruptions by the global pandemic just after launch, the original tight timeline and strict budget were kept in check.

In proactive anticipation of future collaboration with sister agencies, the prudent move was to migrate the COBOL mainframe to the Microsoft C#.NET and Microsoft SQL server platform.

The mainframe wasn’t good at communicating with other systems,” explains Jakob Björklund, Head of IT at Statens Tjanstepensionsverk (SPV). “We had different platforms when we should have the same tech platform.”

SPV needed to complete the migration within a tight deadline and to a strict budget, while restricted by security matters and remote working.

When asked why Björklund, believes the project was such a resounding success he answered:
It’s all about the project management skills with Fujitsu and Asysco, and not as much about the technical migration. Though that was excellent, too.”

Asysco, the true Unisys mainframe solution

August 5, 2021

We occasionally run into companies who accepted an initially attractive-looking offer from Unisys to reduce costs on their mainframe applications.

They get a proposal to run MCP or OS2200 in emulated mode on Intel hardware on-premises or move these workloads into the Cloud where they are supposedly more agile. This solution is advertised as low risk pointing at ‘the risk of failed migrations’ under the Clearpath Forward tag line.

But once they are in this lower-cost environment, the problem becomes apparent: they are now completely stuck in an MCP or OS2200 environment running old COBOL, LINC, ALGOL, or XGEN code bases. Support for these is exceptionally challenging, and people with the right skills are gone.

Big problem! And essentially Clearpath Backward instead of Forward! But it gets worse: now there is also no ROI of migrating off of these programs onto open technologies anymore, and you are stuck with outdated technologies where the only option is to sunset that system and replace it entirely. Ultimately this is much more expensive. Sounds like the good-cheap-fast predicament.

Facing and solving these legacy issues upfront is ultimately much more effective, less disruptive, and the ONLY solution to the problem.

Asysco has NEVER failed a migration, and you can trust us to do the job. We are the true Unisys migration experts. Contact us to understand how we can give you a real Forward solution that helps you.


Why traditional re-hosting your mainframe won’t free you from vendor lock-in

June 4, 2021

Many businesses are losing their taste for mainframes. A volatile world demands an agile IT model and the mainframe—with its heavy licensing and maintenance costs, rigid impenetrability, and reliance on niche programming skills—no longer offers the flexibility and openness that most businesses need.

But it’s no secret that mainframe modernization can be expensive and disruptive. For this reason, many businesses look to re-hosting—where mainframe applications are migrated as-is to a new piece of modernized hardware—as an easy fix solution. This allows them to switch off old hardware and redundant apps to save immediate cost, adopt a more modern distributed IT model as their core architecture and break free from IBM license fees and vendor lock-in.

However vendor lock-in isn’t so simple to avoid, and despite other gains, businesses undertaking mainframe rehosting projects can quickly find themselves breaking free from one lock-in, only to become entrapped in another.

The problem lies in the rehosting approach itself. Mainframe code is complex and unique to the business that developed it and applications often have intricate interdependencies, making the code difficult to unravel. Rehosters address this issue by preserving the mainframe environment on the new hardware using emulation software. This essentially means that the new environment behaves exactly as the old one did, with the code itself remaining largely unchanged. It also means you must keep emulating the environment indefinitely in order to keep using the mainframe apps—and you must do it at cost by buying specific emulation software from your rehosting provider.

There are other issues too: tie-ins to the re-hoster’s migration software usually take away the ability to shop around and the added middleware may cause a drop in performance that must be rectified at additional cost. There are likely to be at least some differences and interdependency issues in the new environment, which means you still need to undertake testing as you would for a more complex refactoring solution. Last but not least, if you later decide to develop or modernize your applications (for example, to run them in the Cloud), you will still need to rewrite the code: it’s essentially starting from square one again.

So, what then is the solution? Simply accepting the limitations and expense of the mainframe and keeping it? Accepting the lock-ins and pitfalls of a faster, cheaper rehosting project? Or giving into a high-risk, high-cost decade-long mainframe rewrite project?

You can, in fact, choose to do none of these. Mainframe modernization is not as rigid as it once was. The technology now exists to automatically convert mainframe code into modern, open-source languages without the need for emulation. This means it can be quickly rehosted in a new environment (such as on an x86 server or the cloud), without the need for additional emulation software, and it will be primed for development using modern coding practices right from day one.

Download our e-Book to find out more about we can help you solve the rehosting riddle, and how Asysco is using unique code conversion technology to provide all of the quick-fix benefits of rehosting, without the long-term lock-in.
