SAP S/0HANA performance improved by 4x on Azure compared to on-prem
Internal cloud competency built: 0 client engineers AWS-certified during engagement
The Challenge
The client was operating 340 mission-critical workloads across 3 aging on-premises data centers, with a data center lease expiration creating a hard 12-month migration deadline. Previous internal migration attempts had stalled due to undocumented dependencies, ERP complexity (SAP S/4HANA), and insufficient cloud expertise within the internal IT team.
The Solution
IntraCodeX led end-to-end migration architecture and execution, beginning with a 6-week discovery sprint using AWS Application Discovery Service to map all 340 workloads and 4,200+ dependencies. We designed a 7-wave migration plan sequencing workloads by business criticality and dependency clusters, executing the plan with a 24-member IntraCodeX team embedded with the client.
Lessons Learned
Early investment in comprehensive dependency mapping (weeks 1–6) eliminated the primary risk that had caused previous migration failures and saved an estimated 14 weeks of rework.
