S/4HANA Migration Factory: Move Legacy Systems Cleanly to SAP S/4HANA

With the cimt S/4HANA Migration Factory, you move the data from one or more legacy systems into SAP S/4HANA in a structured way – cleansed, harmonised and with verifiable data quality. We deliver the migration with Qlik Talend Cloud, preferably on AWS, and support you from analysis to cutover.

Starting point

An S/4HANA migration is first and foremost a data challenge

Whether you are moving from SAP ECC, replacing SAP IS-U or merging several ERP systems: the real hurdle of an S/4HANA migration rarely lies in the new system, but in the data. Grown legacy systems bring duplicates, special cases and archive data that must be transferred cleanly. In addition, you need proof that everything arrived complete and correct. That is why the cimt S/4HANA Migration Factory makes exactly this part predictable.

  • Several legacy systems need to move into one central S/4HANA
  • Data and structures should be cleansed during the move
  • Archive data must be transferred into the new system
  • Migration success must be proven with a post-load report
Approach

Four steps to a verified S/4HANA data migration

01

Analysis & mapping

First, we create transparency about data objects, source structures and special cases in your legacy systems. Then we define the business and technical mapping, selection and transformation rules for the S/4HANA target model.

02

Transformation & cleansing

Next, we extract and consolidate the data with Qlik Talend Cloud. In doing so, we cleanse and harmonise it and also reduce it to what the new system really needs – including archive data.

03

Test migration & validation

After that, we stabilise mapping, data quality and migration logic over several test cycles. In addition, post-load reports show after every run what has arrived complete and correct in the target system.

04

Cutover & hypercare

Finally, we prepare migration windows, approvals and fallback scenarios and support the production migration. We then stabilise operations in the target system. On request, we also extend the pipelines into a data hub or data warehouse afterwards.

Platform, software and consulting from one source

The S/4HANA Migration Factory combines three building blocks into one adaptable solution. As a result, you get not just a tool, but a well-rehearsed migration pipeline. In addition, you gain a data foundation that lasts beyond go-live.

  • AWS: preferred platform with database and runtime environment for the migration – other environments are possible
  • Qlik Talend Cloud: mature software for data integration, data quality and data stewardship
  • SAP expertise built into the tool: for 10 years, cimt has been the Qlik development partner for the SAP components in Talend Studio
  • cimt: many years of experience in SAP migration, data integration and data quality

Replacing SAP IS-U: migration to the Thüga billing platform

Many SAP migrations start with replacing SAP IS-U. For municipal utilities, cimt therefore supports the move to the Thüga billing platform (TAP) – from analysis and mapping through transformation and validation to cutover and hypercare. In addition, the experience from these projects flows directly into the S/4HANA Migration Factory.

FAQ

Frequently asked questions about the S/4HANA Migration Factory

For migrations to SAP S/4HANA from SAP legacy systems such as SAP ECC or SAP IS-U as well as from non-SAP systems. The approach is especially strong when several legacy systems need to be merged into one central S/4HANA system.
Yes. Data can be reorganised, reduced and cleansed during the migration. In addition, archive data can be transferred into the new system in a structured way.
Through post-load reports. After every test and production migration, they show which data has arrived complete and correct in the target system. As a result, data quality becomes verifiable.
AWS is our preferred platform because it provides a suitable database and runtime environment for the migration. However, it is not mandatory – we can also set up the migration pipeline in other environments.
At the core is Qlik Talend Cloud for data integration, data quality and data stewardship. Moreover, cimt has been the Qlik development partner for the SAP components in Talend Studio for 10 years and therefore knows SAP connectivity first-hand.
Yes. For municipal utilities we support the replacement of SAP IS-U, for example with the migration to the Thüga billing platform (TAP).
cimt is a Qlik Elite Partner, a Talend Platinum Partner since 2009, the Qlik development partner for the SAP components in Talend Studio and an SAP Gold Partner. In addition, more than 100 trained Qlik Talend data integration experts combine SAP know-how with experience in data integration and data quality.
