Case Study: Transport for London modernizes SAP and lays the foundation for S/4HANA with Lemongrass on AWS

Transport for London migrates 32 SAP applications to AWS with Lemongrass

Transport for London (TfL) faced the challenge of modernizing its complex, on-premises SAP estate, which was hindered by high levels of bespoke code and limited automation. This drove up costs and reduced agility, preventing a planned upgrade to SAP S/4HANA. TfL selected the AWS Cloud and partnered with Lemongrass to manage the migration and deliver a more cost-effective and agile platform.

Lemongrass successfully migrated TfL's entire SAP landscape, including 32 applications and 252 servers, to AWS with near-zero downtime. The solution delivered immediate savings, refreshed infrastructure, and established the technical foundation for TfL's future transformation to SAP S/4HANA. Lemongrass provided a highly resilient architecture using SUSE for SAP OS clustering to ensure mission-critical uptime for TfL's business-critical systems.
