What does software re-engineering involve?

Re-engineering restores stability, maintainability, and future-readiness to existing enterprise software without having to rewrite the entire code base.

  • You reduce risks and dependencies, especially when key experts are no longer available
  • Your software becomes scalable again and reliable in operation
  • You gain a stable foundation for automation and digital development

In production and manufacturing facilities with critical systems, there often comes a point where the existing software can no longer be reliably maintained or upgraded. When you recognize this, it’s time for a targeted re-engineering effort .

In this article, we’ll show you exactly what software re-engineering entails, why SMEs in industry and manufacturing are particularly affected by it, and how soxes, as a partner, provides structured support along this journey.

Why act now?

  • In many machine, plant, or MES environments, solutions run on outdated platforms (e.g., Delphi, Access, monolithic C++) that are barely scalable and require increasingly frequent maintenance.

  • The loss of expertise (due to retirement or a change of employer) makes maintenance riskier.

  • Costs are rising: Every additional feature becomes a challenge, the time until production stops is getting longer, and the risk of downtime is increasing.

  • Your competitiveness will be significantly reduced; if modern software methods no longer work, you’ll find yourself in a rut.

The four main areas of application for reengineering:

By this we mean the targeted modification, modernization, or restructuring of an existing application without rewriting it from scratch. This is not about short-term fixes, but rather about sustainable system renewal with a focus on operational reliability, maintainability, and efficiency.

An overview:

  • Source code translation: Outdated programming languages (Delphi, PHP, VBA) are replaced with modern alternatives or updated to a current version. However, the system’s structure remains untouched and intact. If languages are no longer supported, the technologies must be maintained independently, which is a time-consuming endeavor.
  • Architecture overhaul: Poorly designed architectures are highly susceptible to errors that can occur during code revision. It is possible that the quality of the application decreases with each revision, as errors are carried over and, in the worst case, exacerbated. Confusing architectures often complicate maintenance, which can result in inadequate support.
  • Structural improvements: It is not uncommon for new features to be hastily added to user software without adapting the underlying logic. Such “add-ons” can create critical gaps in the application, potentially leading to memory leaks or data loss in the worst-case scenario.
  • Data re-engineering: Software re-engineering typically has no impact on the processed data, which is why it can remain untouched. However, re-engineering the data structure is still possible. Revising data models can be useful to avoid compromising the performance of the overall system.

The three approaches to data re-engineering:

  • Clean Up:All data is thoroughly checked for accuracy. Redundancies are eliminated, and all data records are standardized into a consistent format to improve data quality.
  • Extension: Theentities of the data model are either modified or new entities are added to accommodate more information. As with the Clean Up phase, the data is also cleaned and adapted to the new format.
  • Migration: All existing data records are migrated to an existing database or a newly set up database. Reasons for this may include factors such as the performance or compatibility of the database management system.

Re-engineering focuses on optimizing the system structure and improving the application’s usability for the end user. By improving the architecture and underlying structures, it is also possible to reduce maintenance effort and the associated costs.

Focused on Your Benefits

  • Less maintenance, lower costs: A clean architecture makes your software more efficient to use.
  • Greater security and stability: The risks of outages or data loss are measurably reduced.
  • Future-proofed: New features or interfaces can be implemented faster and more cost-effectively.
  • Avoidance of dependencies: Knowledge of the system is not limited to individual people

Who is this approach suitable for?

This approach is ideal for SMEs in the industrial, manufacturing, or logistics sectors that:

  • operate their production or MES systems on outdated software,
  • have experienced or are facing the departure of developers or IT managers,
  • need a stable foundation to implement future innovations, such as AI or IIoT.

Why is this the case with re-engineering?

  • We analyze not only code, but also processes, roles, and technical frameworks.

  • We systematically assess all risks that could jeopardize our day-to-day operations.

  • We clearly identify which areas are stable and where modernization is needed.

  • We provide concrete steps and recommendations as early as the analysis phase.

  • We bring extensive expertise in MES, inspection processes, production lines, and machine integration.

  • We operate in accordance with ISO 27001 and ensure a high level of security and reliability.

  • We have experience with Delphi, Access, C, C++, VBA, PHP, Java, and Microsoft environments.

  • We take responsibility and rely on clear processes for analysis, stabilization, and operations.

Give your system a new level of stability!

If you know that your application is difficult to scale, our analysis phase will show you exactly where the risks lie and what steps make sense.

  • Clear technical assessment of risks and potential
  • Concrete steps for stabilization and modernization
