“Software Reengineering and Evolution” is an evergreen in software development. However, new technologies and possibilities in the area of development lead to ever new challenges in dealing with the existing software.
The expert group Software Reengineering and Evolution (SRE) within the Gesellschaft für Informatik (GI) - the German-speaking professional society for computer science - deals with all aspects of software reengineering, software maintenance and software evolution. In principle, this includes all activities whose goal is analysis, visualisation, evaluation, improvement, migration and further development.
Workshop Software Reengineering & Evolution (WSRE)
With the conference series Workshop "Software Reengineering and Evolution" (WSRE), the SRE expert group aims to bring together practice and research and to promote professional exchange with a variety of current topics.
Practitioners and researchers are cordially invited to report on experiences, projects, research results, methods, tools and “war stories” in this field at the WSRE, to present their current work and to discuss it constructively in an open environment.
WSRE 2025 from 09.-11.04.2025
27. WSRE 2025 took place from 09.-11.04.2025 in Bad Honnef!
Delta was there with a presentation on April 9, 2025 at 2 p.m.:
Analysing a Big Ball of Mud
The original design of an application often gets lost over the decades, creating a “big ball of mud” instead. Such applications are difficult to maintain and even more difficult to modernize. With AMELIO Logic Discovery you can analyse applications and prepare for clean-up and modernization projects.
How? We presented and summarized this for you at the Software Reengineering and Evolution (WSRE) workshop of the GI Software Reengineering (SRE) specialist group.

The clean design of an application often gets lost over decades. Applications arise where design specifications are not met. Such applications are difficult to maintain and even more difficult to modernize. AMELIO Logic Discovery helps identify design violations in an iterative process.

Take the opportunity for direct exchange and networking. Participation is open to everyone. All information about the workshop and how to submit contributions can be found here.
WSRE 2024
The 26th Software Reengineering & Evolution Workshop of the GI Software Reengineering (SRE) specialist group took place on 29 and 30 April in Bad Honnef.
How to Quickly (Re-)Gain the Knowledge about Your COBOL Applications
At this year's tool session, Dr. Daniela Schilling, CEO of Delta Software Technology, presented:
‘When the English Dictionary is Not Enough - Understanding COBOL Applications with AMELIO Logic Discovery’
In order to (re)understand large, complex COBOL applications that have grown over decades, it is not enough to be able to read the code. Instead, it is necessary to abstract from technical details and gain knowledge at a glance. Appropriate views of the application are also required for various tasks. We present AMELIO Logic Discovery, a tool for automated knowledge (re)gain.
You couldn’t attend? No problem!
Contact us directly and find out how AMELIO Logic Discovery can help you to re-understand your COBOL applications.

You probably know all the good reasons to replace your IMS databases:
- Reduction of cost and maintaining multiple database technologies
- Lack of flexibility of IMS databases
- Diminishing know-how and specialists
- No successors available
- Difficult connection with new technologies like Mobile Cloud etc.
The hurdles for replacing IMS-databases are huge and the applications are running smoothly. These, often mission critical, applications are big, complex and the documentation is in most cases not sufficient for the task ahead.
From hierarchical to relational - 100% automated
The aim is to convert the application to clean SQL, i.e. not to "translate" the IMS accesses to SQL at runtime using a proprietary intermediate layer. The customised, fully automated transformation with AMELIO Modernization Platform guarantees the consistent and audit-proof migration of your COBOL and PL/I applications.
How can you replace your IMS system safely and efficiently?
Delta Software Technology presented a reliable solution that gives you the following advantages:
- You are supported in defining the new relational data model.
- The transformation is carried out securely and completely automatically - with automatic integration of the changes from the parallel ongoing development.
- The testing effort is drastically reduced thanks to the complete automation of all changes.
- There is no footprint and no vendor lock-in.
Review of the Webinar
We were able to win Gothaer Solutions GmbH and Provinzial Versicherung AG for this webinar. The participants took the opportunity to ask their questions directly to the companies' experts who have already successfully replaced their IMS databases.
Dr. Daniela Schilling (CEO, Delta Software Technology GmbH) presented the Delta solution AMELIO:
"Automated and Secure Migration from IBM IMS/DB to Db2 with AMELIO Modernisation Platform"
In the subsequent discussion, experts from Gothaer and Provinzial were on hand to answer questions from the audience. They reported that production and development continued undisturbed and that the migration project ensures the maintainability and future viability of the systems. Processes have been standardised and, thanks to targeted and, of course, automatically implemented optimisation of the access logic, individual applications now run even more efficiently than with the hierarchical database system.
When asked what they would do differently next time, both customers agreed: less testing and no more manual migration! This would save them even more time, money and nerves, because Delta's automated solution simply works.

Gothaer migrates its IBM IMS Databases to IBM Db2 together with Delta Software Technology
Gothaer Systems migriert zusammen mit Delta mehr als 400 IMS-Datenbanken zu Db2. Durch den Aufbau einer passgenauen Factory konnten notwendige Schritte zur Transformation automatisiert, gut kalkuliert und risikoarm durchgeführt werden.
„By migrating from IBM IMS/DB to IBM Db2 together with Delta, we have successfully mastered the next big step in the ‘Smarter Mainframe’ project.“
Burkhard Oppenberg, CIO, Gothaer

From IBM IMS/DB to Db2 - Provinzial realizes complete Migration
With the tools and services from Delta Software Technology, Provinzial Rheinland finished the complete application and data migration from IBM IMS/DB to IBM Db2, automated and securely, of over 75 IBM IMS databases and over 36,000 artefacts.
"The guaranteed operational “smoothness” in the project, despite the complex modernization, is certainly a unique feature of the solution.“

The independent IT consulting company itemis AG hosted the webinar "Legacy Systems in Flux - Automatic Migration?" on 27 July. Our managing director Dr. Daniela Schilling was invited as a speaker.
How can legacy applications be made fit for the future and is an automatic migration from COBOL to Java effective?
The experts presented their solutions, approaches and experiences in short presentations. This was followed by perspectives and opinions on challenges and best practices. The automatic language transformation from COBOL to Java was discussed in a particularly lively and controversial manner.
The answers to the following questions were considered crucial for the success of such projects:
- Are the migrated sources still maintainable or does the automated migration inevitably lead to a "Jabol" disaster?
- How do you test the migrated applications? And what hurdles have to be overcome?
As an alternative to an automatic language transformation, Dr. Daniela Schilling presented an automated modernisation in manageable steps and with a suitable solution for each sub-application and explained specifically why a 1:1 language transformation leads to additional problems.
Please also have a look at our slides with detailed information on our solution and proceeding:
