Managed Legacy Service
Future-proofing business-critical legacy systems
Stable operation and plannable modernisation from under one roof
Many organisations are facing the same problem: their legacy systems safeguard their business operations, but prevent innovation and drive up costs. Whilst security and compliance requirements are becoming stricter, in-house expertise is becoming scarce, and there is increasing pressure to incorporate new digital services quickly and reliably.
7P’s managed legacy service is here to help with this dilemma: it combines stable operations with a clearly structured pathway to modernisation, without putting your day-to-day business at risk.
Our service portfolio – modular and reliable
Operation and maintenance
As part of our application management services, you get 24/7 monitoring with fast response times for maximum system stability as well as proactive maintenance. Professional incident and change management ensures that your business-critical systems have maximum uptime.
AI-powered automation
Modern AI technologies automate repetitive tasks such as monitoring, incident analysis or code reviews, reducing manual work, speeding up processes and increasing operational efficiency. This allows any sources of error to be identified at an early stage and your legacy systems will remain stable, powerful and future-proof.
Integration and modernisation
AI-powered requirements analysis and stable interfaces enable a step-by-step transformation without operational risk. Experts will analyse your legacy software and develop custom integration solutions. A legacy system assessment forms the basis for how to proceed.
Expertise and know-how
Business continuity is also ensured in the event of staffing changes through systematic knowledge preservation and continuous documentation. By combining specialised legacy expertise with modern approaches to generative AI, processes can be continuously optimised.
Security and compliance management
IT security management and automated compliance reports ensure that all regulatory requirements are observed and contribute to business continuity as well as governance, risk and compliance (GRC), e.g. for critical infrastructures and digital services.
Why is legacy management crucial nowadays?
When it comes to critical infrastructures and digital services, legacy applications continue to perform important tasks in process automation, data storage and connection to administrative processes. As IT security risks are increasing and regulatory requirements are becoming more complex, maintenance costs are continuously rising.
What’s more, the necessary expertise is often only available internally to a limited extent. Your IT teams are under enormous pressure: they have to ensure operations remain uninterrupted 24/7, guarantee short response times in the event of a disruption and provide seamless monitoring. These requirements tie up considerable resources and jeopardise your organisation’s ability to innovate.
How you can benefit from the managed legacy service
Reduce operational workload with strategic added value
Standardised processes reduce operational complexity, allowing your IT teams to direct their focus back to innovation. Scalable operating models safeguard budgets and enable targeted IT outsourcing in complex legacy environments.
Comprehensive risk mitigation and compliance
Professional security management, complete documentation and continuous monitoring of critical systems prevent unplanned downtimes and the associated costs, and significantly reduce regulatory risks.
Future-proof modernisation
Integrating modern technologies, developing internal skills and gradually transforming systems without interrupting business all make sure your organisation is best prepared for upcoming requirements.
Industry expertise and technological innovation
We meet complex requirements and combine this with AI-powered automation, intelligent staffing models with nearshoring options, and advanced analytics for quantifiable process and cost optimisation.

Typical usage scenarios
A managed legacy service is proving key for companies with critical infrastructures that need to ensure regulatory compliance for legacy systems and reportable procedures. Such an approach is particularly relevant for in-house developments that are intensive to maintain in IT landscapes with interfaces that have evolved over time and high requirements when it comes to expertise. Systems where downtime would have serious consequences also reap the benefits.
A managed legacy service is important when linking legacy systems with cloud infrastructure as well as when operating outdated platforms with legacy ERP systems or administrative processes that are required for operations. After the departure of key staff members, it ensures the necessary business continuity in IT environments where new staff are limited.

Our 7-step modernisation strategy
Legacy systems can be gradually transferred over to modern architectures without jeopardising ongoing operations. The tried-and-tested 7-step strategy is a flexible process model for sustainable system modernisation. Depending on your starting situation and target image, you will go through some or all of the following steps. Combining operation, optimisation and subsequent transformation is particularly effective.
1. Encapsulate: creating interfaces
Existing system functions are made available via modern interfaces (APIs) without changes being made to the core system. This means that integration with new applications can be done quickly without changing the legacy architecture directly.
2. Rehost: modernising infrastructure
The system is migrated to a modern infrastructure (e.g. cloud, containers) without making any adjustments to the application code. This reduces technical dependencies and increases scalability.
3. Replatform: changing platform with minimal effort
Slight adjustments in the code allow the application to be transferred to a new runtime environment, reducing operating costs and creating a more stable technological base.
4. Refactor: optimising technology
The code is revised and improved without the application’s functional behaviour being changed. This makes the system significantly more easy to maintain, high-performing and secure.
5. Rearchitect: rethinking structure
The system’s structure gets redesigned to meet future requirements, such as scalability, modularity or cloud-native capability. This step is key for modern system landscapes and enables agile continuous development.
Steps 6 and 7 are optional. Whether or not your company needs to take these steps depends on the results of the analysis. However, we recommend them in many cases, especially when profound technological or technical changes are required.
6. Rebuild: redeveloping with a tried-and-tested base
The application gets completely redeveloped based on existing technical requirements so technological freedom is possible with the same business focus.
7. Replace: complete system replacement
The old system is replaced by a new solution that not only meets existing requirements, but also incorporates new functions, business models or processes with a targeted approach.
Our services think ahead – thanks to integrated AI optimization.
