SAP S/4HANA Upgrade

An SAP S/4HANA upgrade moves your system to a newer release, such as S/4HANA 2023, to stay in mainstream maintenance and unlock new functionality and AI capabilities. We plan and run the upgrade end to end: custom-code remediation, regression testing, cutover and hypercare, often adding the business improvements that justify the upgrade.

The need

The company ran a stable S/4HANA system on an older release that was leaving mainstream maintenance, and structural changes in the business needed new processes.

What we did

  • Upgraded to SAP S/4HANA on-premise 2023 using a shell conversion
  • Remediated custom ABAP code and discontinued the HCM component
  • Ran workshops with business users and configured improvements in finance, costing, production, sales and procurement that formed part of the upgrade business case
  • Carried out cutover and go-live on the new release

The result

Live on S/4HANA 2023 without any significant issue, with the improvements the business case promised. We now provide AMS, including RICEF developments, process changes and automation.

Questions

SAP S/4HANA Upgrade, answered.

How often should we upgrade S/4HANA?
SAP releases new on-premise versions on a regular cycle with several years of mainstream maintenance each. Most companies plan an upgrade every few years; we help you time it.
Can AI help with upgrades?
Yes. AI-assisted tools now help with custom-code analysis, test generation and data preparation, reducing time and risk.
What is a shell conversion?
A technique that upgrades a copy of your system without business data first, so code and configuration can be remediated before the production upgrade.
