Companies often do not switch off legacy systems because they fear data loss and do not want to historize or migrate their legacy data. The migration of data is also an unpopular topic when switching applications to the cloud or introducing new software. Such projects do not have a good reputation. Those who rely on standardized and established procedures can save time and money through data analysis and migration.
There are IT projects that many IT departments shy away from and like to put off: data migration and data historization. These projects have a reputation for being complex, risky, costly, and time-consuming. But at some point it can no longer be avoided, for example when legacy systems are switched off, applications are migrated to the cloud, or software providers launch completely new systems on the market. A current example of this is the inevitable switch to SAP S/4HANA by 2025, by which time SAP customers will be faced with the challenge of migrating their data to the new system and possibly to the cloud at the same time.
What is usually perceived as a risk actually offers opportunities to free oneself from unnecessary data loads and costs. This is because the migration and historization of data can result in considerable savings potential. Those who switch off legacy systems can generally save between 60 and 80 percent of the costs. When switching to SAP S/4HANA, for example, the costs for operation, management, and maintenance of SAP systems are reduced by up to 80 percent. This gives you freedom for innovation.
Those who manage to separate themselves from their own developments and thus eliminate duplicate or unused legacy applications make up to 85 percent of the data superfluous. After all, legacy systems are often a historically grown structure in which you store a lot of data without structure, redundantly, and in silos. The consequential costs for operations, related personnel, and security and compliance risks can therefore take on enormous proportions.
Managed application retirement services also include the subsequent service for platform operation in the private or public cloud. If required, T-Systems can also take over operation in a dedicated environment in the private or public cloud after data migration and historization. The data remain available and searchable for 30 years or longer. The data services meet the requirements of the GDPR and the specifics of the DACH region such as data storage regulations (GoBD) in Germany, the Code of Obligations in Switzerland, or the Federal Tax Code in Austria. And they are regularly adapted to new legal requirements.
Historization refers to the intelligent decommissioning of systems, detached from previous applications. This is also the difference to traditional archiving, in which the archive is still accessed via the original application. Historization is all about understanding the data logic of applications, however complex they may be. In addition, the criticality and availability requirements of the data as well as the respective data strategy of the company are taken into account. If companies use the Managed Application Retirement Services, data and documents are transferred to a highly secure, dedicated cloud environment while taking the respective corporate requirements into account. All individual compliance requirements can also be easily implemented in the new environment. Legal requirements such as the EU GDPR and GoBD conformity are automatically fulfilled.
Be it mergers, corporate acquisitions, business transfers, leveraged takeovers, outsourcing and insourcing, spin-offs, carve-outs, or corporate cooperations: even when you switch off legacy systems, for legal reasons you must continue to store data for decades in such a way that targeted access and deletion is possible at any time. In order to be able to do this, data must be migrated and historized.
The starting point for the migration of the data is a standardized project with a proven, methodical approach. All data and documents are extracted from the existing applications and automatically transferred to a central database in the cloud. This applies to financial data, product information, reports, and other documents. Even existing archive data and external data can be integrated.
The logic of the legacy data separated from the applications is carried over to the new platform. This means that access to the data, which can no longer be changed, is as intuitive and fast as usual. Authorized users can visualize the data according to various criteria or create evaluations and reports. To ensure the success of the transfer, historization is provided with appropriate, additional services, such as project, risk, quality, and change management.
