Transparency about your legacy system before you decide
A lack of transparency makes every change difficult. We analyse your legacy system and create a reliable basis for decisions.
As long as nothing changes in the system, everything runs. That is exactly the problem.
Most legacy systems have been doing their job reliably for years. Their condition only becomes visible when something is required: a new interface, a security patch, a migration decision or an AI use case based on existing data.
That is when it becomes clear what is missing. The documentation has gaps, key relationships can no longer be traced, and the knowledge lies with just a few people. A small change becomes a risk analysis, a planned migration becomes a black box.
- Incomplete documentation
- Knowledge held by just a few people
- Decisions are postponed or based on assumptions
Why is legacy management crucial nowadays?
Many business-critical applications run stably as long as they remain unchanged. As soon as adjustments are needed, it becomes clear how little transparency there is about the system. It is often unclear how components are connected or what effect a change will have. Even small interventions become time-consuming and difficult to plan.
At the same time, the demands on operations are increasing. Security, availability and traceability must be ensured, even if the system base was not designed for this. If key people are absent or move on, additional risks arise.
The result: you are expected to assess effort, risks and options for management, audit or business departments without having the basis to do so. This is exactly where we come in.
How do we proceed without interrupting your operations?
The right next step depends on how well the system structure, dependencies and risks are understood. That is why we start with a reliable assessment. After that, operation and modernisation are guided by what your system needs.
Assess and decide
You need to decide on migration or replacement, but cannot reliably assess the effort and risks? We make the structure and dependencies traceable and provide a sound basis for decisions you present to management and business departments.
Stabilise and operate
If the system remains in use but causes increasing effort, we keep ongoing operations reliably manageable. This helps when disruptions occur repeatedly, maintenance depends on individual people or your team is tied up in day-to-day business.
Migrate and renew
If infrastructure or architecture becomes the limiting factor, we develop a feasible modernisation path. This applies, for example, when technologies are no longer supported, new requirements are difficult to implement or integrations are only possible to a limited extent.
Our services for your legacy system
Eight services in three areas: assessment and basis for decisions, stabilisation and operation, and migration and technical renewal.
Legacy Fast Check
Analyses your system and makes its structure, interfaces and dependencies traceable. It shows risks in operation and maintenance, estimates the effort for changes or migrations and compares realistic options. Result: an assessment overview, a risk catalogue and a weighted action roadmap.
Legacy GenAI Quick Call
Assesses where AI can be useful in your system: possible use cases, suitability of data and structure, support with analysis, documentation or further development. It clearly rules out unrealistic expectations.
Legacy Knowledge Transfer
Preserves experience-based knowledge before employees leave. AI agents ask structured follow-up questions and prepare the answers. The technically reviewed knowledge is linked to code, tickets and documentation and made usable for employees and AI assistants.
Legacy Guard
Stabilises ongoing operations: maintenance and troubleshooting during operation, structured analysis of disruptions instead of pure reaction, targeted measures for more stability and remediation of known weaknesses by priority.
Legacy Full Auto
Takes over the operation, maintenance and further development of your system completely and implements changes in a controlled manner. Your internal teams are relieved of operational tasks and gain room for new projects.
Legacy Modernization
Adapts architecture and code in a targeted way: we clarify which parts can be retained, reduce technical limitations and improve maintainability and extensibility. Step-by-step adaptation instead of complete redevelopment.
Legacy Lift & Shift
Moves existing systems to the cloud or to new operating environments. The business logic is retained and changes to the code remain minimal. This improves scalability and operating options.
Legacy AI Retrofit
Extends existing systems for automation and AI: data becomes available for new applications, new interfaces connect modern architectures, and existing processes can be automated.
How does AI help with legacy systems?
What do you use AI for in legacy systems?
AI helps to evaluate code, documentation and data structures in systems that have evolved over time more quickly. We use it to analyse code and technical dependencies, for documentation, for evaluating existing data, for preparing changes or migrations and for generating test cases.
What changes through the use of AI?
Above all, speed and traceability. Relationships within the system become visible more quickly, documentation can be built up more consistently, analysis effort decreases and existing knowledge becomes easier to use.
Does AI replace the decision about your system?
No. AI helps to understand existing systems more quickly, but it does not replace the decision on how to deal with them. Architecture decisions are not made automatically, security and compliance requirements continue to be checked, and responsibility for changes remains with the project team.
How does 7P use AI in practice?
In a targeted way and embedded in existing processes. We review the results and assess them from a technical perspective. AI is used within defined quality and approval steps.
