SAP Go-Live: How to get started with live operation
An SAP go-live is an important moment in any project. Regardless of whether it is a new SAP implementation or an S/4HANA conversion – the transition to live operation must be well prepared. With clear processes, reliable support and sensible aftercare, this step is successful.
What does “Go Live SAP” mean?
The term “Go Live SAP” refers to the moment when the new system goes into real operation. When it is introduced, a completely new system starts. In the case of a conversion, an existing system is technically converted – usually over a weekend.

What is the difference between introduction and conversion?
Both are large projects, but with different requirements:
- SAP implementation: New system, new processes, new database
- S/4HANA conversion: Existing system will be converted, many data and processes will be retained
Despite the differences, there are many common tasks that should be planned carefully.
The SAP Go-Live Checklist – Prepared Step by Step
A good checklist helps to keep track of everything. These points should definitely be done before the go-live:
- All tests completed (e.g. integration, functions, interfaces)
- User roles and rights set up
- Training of key users carried out
- Data migration tested and secured
- Cutover plan created and agreed
- Emergency plan prepared
Tip for S/4HANA: In addition, pay attention to custom code, interfaces and the SAP compatibility checks.
Example of a Final Cutover Checklist
Purpose of the Checklist – The Final Cutover Checklist serves as a release basis for the go-live of an SAP system. It ensures that all essential areas have been checked and approved before the system starts. The checklist complements the detailed cutover planning with an overview of the approval criteria.
| Range | Acceptance criteria |
|---|---|
| Technical infrastructure | – Stress tests successful – Support pack level correct – 3 cutover test cycles completed – Infrastructure tested |
| Functional system design | – Configuration complete – Integration tests successful – CAT completed |
| Development system | – Development (SAP, AIM, interfaces) completed – Tests and regression successful |
| Permissions | – User accounts set up – Tests successful |
| Data cleansing | – Master data validated (employees, organization, positions, etc.) |
| Conversion | – Programs complete and tested – Procedure documented |
| Training | – Materials and instructions complete – End-users trained |
| Organizational readiness | – Change management completed |
| Project | – Management available – Approvals documented |

SAP Go-Live Support – quick help for a secure start
After the go-live, there may be questions or problems. That’s why good SAP go-live support is so important. It ensures that faults are quickly detected and resolved. These include:
- Contact persons in the support team
- Clear troubleshooting processes
- Technical monitoring (e.g. system performance, interfaces)
- Close cooperation with key users and departments
The stabilization phase – after the go-live, it continues
The go-live is just the beginning. In the stabilization phase , it becomes clear whether everything really works. Now it’s about:
- Troubleshoot quickly
- Implement initial improvements
- Collect and evaluate feedback
- To continue to support the departments
This phase often lasts several weeks. It should be planned and supervised in the same way as the go-live itself.
Conclusion: Well planned is half the battle
Whether it’s a new SAP implementation or S/4HANA conversion – with a clear checklist, reliable support, and well-thought-out follow-up, the go-live with SAP is a success. Those who take these phases seriously lay the foundation for stable and successful operations.
