Future-proofing your IT infrastructure: Lifecycle management of end-of-life systems

In today’s fast-paced digital age, it is crucial to keep IT infrastructure up to date at all times. Organisations face the challenge of finding solutions that go far beyond simple maintenance. Effective lifecycle management plays a central role in this. An important aspect of this process is the management of ‘End of Life’ (EOL) for software and systems. Current examples include Windows Server 2022 and Ubuntu 22.04 LTS, which will lose active support in autumn 2026 and spring 2027 respectively.

This article examines the challenges associated with the end of support for IT systems. It outlines the available options and shows how organisations can use the impending EOL to future-proof their IT infrastructure.

What is lifecycle management in relation to end of life?

Lifecycle management in IT refers to the entire process of managing a piece of software or a system, from deployment through to decommissioning. For example, when a server’s operating system reaches its ‘end of life’, this means that the manufacturer no longer provides updates, patches or technical support for it. This can lead to security and stability issues for the applications running on the system. Microsoft reports that there are approximately 60,000 server systems actively operating with an EOL operating system in Germany. There are no exact figures for the Linux server landscape, but the number of EOL operating systems is likely to be far greater. This poses an extreme security risk.

The following points are relevant within the context of lifecycle management in view of a platform reaching its EOL:

1. Inventory, assessment and risk analysis:
   • Checking all servers running the operating system in question.
   • Assess the critical applications and services that depend on these servers.
   • Identifying risks associated with the continued operation of an obsolete operating system, such as increased security risks, compliance issues and the potential loss of support and compatibility.
2. Planning the migration/upgrade:
   • Developing a detailed migration plan for a supported operating system. This could involve upgrading to a newer version of the current operating system or migrating to a different operating system. Consideration should also be given to changing the IT infrastructure and updating applications.
3. Data backup:
   • Carry out a full data backup of the affected servers before any changes are made, to prevent data loss.
4. Migration/upgrade:
   • Carry out the migration or upgrade in accordance with the agreed plan. This should be done on a server-by-server or application-by-application basis to minimise risk and downtime.
5. Testing and validation processes:
   • Carry out tests to ensure that all applications and services are functioning correctly on the new platform.
   • Validate the migration through careful monitoring and testing following implementation.

A Managed Service Provider (MSP) plays a central role in lifecycle management, particularly when operating systems or software reach their ‘end of life’. The MSP proactively monitors the systems in use to identify impending EOL dates and notifies customers of risks at an early stage. They provide strategic advice and planning, draw up detailed migration plans and make the necessary resources available. To ensure a smooth transition, they coordinate and manage the entire process, thereby keeping downtime to a minimum. This ensures that the company’s IT infrastructure remains up to date and secure at all times.

Options for dealing with EOL systems

There are various options for making ‘end-of-life’ systems future-proof. Organisations can take measures such as upgrades, migrations or application modernisation, or, where appropriate, utilise extended support. These strategies help to minimise risks, enhance security and improve the performance of the IT infrastructure. A well-thought-out plan is crucial for long-term success. MSPs proactively support the implementation of the chosen strategy and put it into practice for companies.

1. Upgrade

Upgrading systems not only offers protection against risks but also presents an excellent opportunity for optimisation. Through systematic upgrades, you can significantly improve the security and performance of your systems whilst simultaneously enhancing the overall effectiveness and efficiency of your IT infrastructure. A well-thought-out upgrade plan helps to minimise downtime by setting out a clear strategy for updating the systems. This ensures that all affected components are seamlessly updated to the latest version. Furthermore, a structured approach facilitates the rapid restoration of operations following the upgrade, thereby ensuring business continuity. The challenge with this option is that it must be ensured from the outset that existing applications run smoothly on the new operating system.

2. Migration

Migrating systems offers protection against risks and the opportunity to optimise and further develop the IT infrastructure. A key advantage lies in the flexible approach: by deploying a parallel system, applications can be gradually migrated to the new platform and thoroughly tested. This is particularly useful when it is not immediately clear whether the applications will function smoothly on the new operating system. During migration, configuration adjustments can be made, and the applications can be comprehensively tested to ensure they work flawlessly. This method minimises downtime and ensures that the transition to the new platform takes place without disruption and with a high level of reliability. This not only enhances security but also ensures the long-term performance and stability of the IT infrastructure, much like planned upgrades.

3. Extended Support for Operating Systems

If a direct upgrade or migration is not immediately possible, many operating systems offer extended support for a fee. This service includes security updates and critical bug fixes, even after the EOL date. This gives organisations valuable time to thoroughly plan and implement a more comprehensive migration.

Extended support is particularly useful for organisations with complex IT environments where an immediate upgrade or migration is not realistic. It provides a temporary solution, allowing organisations to develop and implement their long-term plans at their own pace without exposing themselves to immediate security risks. This support ensures that critical systems continue to run securely and stably, whilst allowing sufficient time to develop and implement a thorough and well-thought-out migration strategy.

4. Application modernisation

Application modernisation goes far beyond simple upgrades or migrations and involves a complete overhaul of the IT architecture. Options include migration to the cloud, the use of containers and the adoption of serverless architectures.

Migration to the cloud offers not only flexibility and cost-efficiency, but also high availability and reliability. Thanks to these modern approaches, organisations can respond quickly to changing business requirements and implement new applications and services with minimal effort.

Container technologies such as Docker and Kubernetes enable a platform-independent and consistent runtime environment, whilst serverless architectures such as AWS Lambda or Azure Functions eliminate the need to manage infrastructure and charge only for the computing power actually used.

By modernising their IT architecture, companies can boost their efficiency, minimise downtime and remain competitive in the long term.

Conclusion

It is crucial for a company’s success that its IT infrastructure remains up to date and secure at all times. Managing end-of-life (EOL) for operating systems and software presents a particular challenge. To minimise the risk of potential attacks, these should be thoroughly reviewed. This is particularly important as AI makes it considerably easier to carry out attacks. Outdated systems should therefore be updated promptly or replaced with supported versions.

This is where Managed Service Providers can make a valuable contribution. The MSP proactively monitors the systems in use, providing early notification of upcoming EOL dates and the associated risks. They provide strategic advice and draw up detailed migration or upgrade plans to carry out systematic upgrades or migrations. In addition, the MSP provides the necessary resources and ensures comprehensive data backups.

Key options for managing EOL systems include upgrades, migrations and application modernisation. The MSP coordinates and manages the entire process, minimising security risks and downtime. This ensures that the company’s IT infrastructure remains secure and up to date at all times, guaranteeing long-term efficiency, security and competitiveness.
