Smooth data migration process to SAP S/4 HANA

Tentive / Customer Cases / Smooth data migration process to SAP S/4 HANA

To migrate their legacy ERP system Microsoft Navision to SAP S/4 HANA, a supplier of high-quality garden products hired a Tentive data migration specialist to complement their team. A good end result was achieved in just six months. Read more about how it worked.

The process

After almost two years of preparation, the phase of UAT (User Acceptance Testing) had arrived for the organisation. This involved too much work for just the Data Migration Lead. Together with the client, it was decided that the Tentive Data Migration Consultant would focus on the data objects materials, parts lists, routing and production versions, focusing on mapping, conversion of load sheets and validation of data. As the project was already in full swing, it was necessary to find a way quickly and work at full speed. The acceptance environment would be loaded in June, giving only one month to get stuck in. For the parts lists, for instance, a lot of work had to be done from scratch. The deadline was met and all data objects could be loaded in June, after which the acceptance test started in July. For the test phase, the company had rented an external location for three weeks, where 30 people were continuously testing. An exciting and hectic phase!

The result

In addition, the Tentive Data Migration Consultant became temporarily responsible for resolving questions around master data and data migration. The various problem sets could be picked up and solved quickly. While most other company employees were also enjoying their well-earned time off, the data migration team went to work hard to prepare the load files for production. This phase was successfully completed in August, after which the load files could be loaded from September onwards. Data was loaded up to and including and during the go-live. Master Data was loaded first, followed by Transactional Data, as this can change up to the last day (open items, orders and stocks). The result was a successful go-live.

Team effort

To complete the project properly, three more weeks of hypercare were provided, after which everything could be smoothly transferred to the business. Thus, an intensive phase of a migration project was successfully completed in six months. It was a real team effort and very pleasant cooperation; both with the Data Migration Lead and with employees from the various teams and departments such as Master Data, Production, Procurement, Logistics, Finance and Customer Service.
