SAP S/4HANA has flexible data structures, modern UI with accurate and near-real-time analytics. The business reasons for migration are plenty, and you can find some of them in my blog here. Once you’re past the business justifications stage, it’s now time to start planning for an actual migration. There again, you have three primary approaches that I highlighted in my blog here.
This short blog would highlight some high-level steps to consider when you’re ready to proceed down your chosen migration path. Note that migrating to SAP S/4HANA is unlike an ECC upgrade as it requires an understanding of (1) business structure, (2) technical impacts, and (3) updated skillsets.
The first step in this migration journey should be an S/4HANA Migration Assessment. The assessment should cover the following areas –
– Impact of the migration on your standard business processes and any custom code.
– Effort estimate for the system conversion based on your chosen migration approach.
– The number of corrections required and effort estimates for the same.
– Impact analysis of the standard vs. custom code and any cloned custom code that needs to be modified.
– Replacements for transactions that the simplification removed.
– Effort estimate for unit tests, progression tests, and regression tests.
– Identify all the Fiori applications based on the scope.
– Effort estimates for all impacted interfaces, including 3rd party integration points.
– Types of skill sets needed for the system conversion
– Resource skills based on the most-used modules and business processes.
– Impact on the roles and users by module.
– Overall project plan and timeline based on the total effort and allocated resources (both from client and system integrator).
An SAP S/4HANA assessment should provide a clear picture of the full scope of your project so you can start the actual system conversion process. At inoBrix we offer a full SAP S/4HANA assessment that includes customer discovery workshops and an S/4HANA roadmap as the final deliverable addressing all the items listed above. We invite you to reach out to schedule a consultation.
