After more than 20 years on SAP IS-U, ENGIE decided to migrate part of its customer base to SAP S/4HANA Utilities. All of its B2B customers were affected. They had to be identified in the nearly 40 TB system and transferred to SAP S/4HANA Utilities.
The goal was to completely migrate the B2B data, including five years of data history, in just 10 months, with a maximum business interruption of 40 hours. Tata Consultancy Services provided support, bringing Natuvion on board as migration experts.
