Legacy systems

Legacy System | Legacy
Legacy system is a term that refers to an old or obsolete computer system, software program, or technology that is still in use because it is still necessary for some essential business or administrative function, but which is difficult to maintain, or update, because of its age or lack of compatibility with newer systems.

These systems are often characterized by their complexity, inflexibility, and lack of support or documentation. In many cases, legacy systems have been in use for many years and may have been developed using outdated technologies and programming languages, making them difficult to maintain or modify.

Despite these challenges, many organizations continue to rely on legacy systems as they provide critical data and functionality, and may need to invest in dedicated resources and expertise to keep them running smoothly.

BITS experts have worked with legacy systems in a variety of projects. A selection of case studies and references can be found below.

Replacement of existing quality management software by introduction of web-based in-house development

In this project, an outdated quality management software was replaced by an in-house development from another Group subsidiary.

Cost savings by reducing the amount of memory consumed by SAP systems, establishing monitoring and increasing performance

The goal of the SAP project was to reduce existing storage consumption and thereby save costs in the seven-digit range per year, both in the short term and in the long term.

Development of a web application and a mobile app to improve breast cancer patient follow-up.

Together with Apps in Medicine GmbH, AOK Bayern, DAK Gesundheit and Siemens Betriebskrankenkasse (SBK), under the direction of the Klinikum rechts der Isar of the Technical University of Munich (MRI), BITS participated in the PRISMA study as a consortium partner for the technical infrastructure.

Transition Management

We were able to profitably apply our experience in the IT infrastructure sector during the relocation of the complete data centers of a major corporation. The particular challenge was the relocation of the complete server infrastructure within one year during ongoing operations and the resulting high complexity of the processes to be planned.

Fullstack web development

Fullstack web development is one of our core competencies and has been practiced by our staff for over 25 years. Besides the excellent expert knowledge in backend and frontend development of normal or highly complex web applications, we are also specialized in all related technologies, processes and methods as well as architecture and operation of web applications up to high availability.
