But, how to migrate from the older version of SAP – ECC data base & launch S/4 HANA for your Organization? What are the key steps involved? How the roadmap is planned & when does execution takes place for S/4 HANA Data Migration? What are the limitations & S/4 HANA Migration tools? Is it really possible to do it, without losing the originality of the product & project?  SAP S/4 HANA migration isn’t so complex that execution will not be done but not so easy to be deployed. A smart access service & Migration service is what will make the process very robust & active to be used. But this cannot be done without a roadmap & strategy. SAP S/4 HANA is migrated from ECC. Pre-migration steps are the most important ones. Before getting transformed, major requirements are to completely understand the business requirements.

How Amdhan is contributing towards SAP S/4 HANA Migration from ECC database & what are the Tools used by our Team for SAP S/4 HANA Migration?

We keep a Maintenance Planner that checks the system with respect to the business functions, industry solutions, add-ons. While Migrating from ECC to SAP S/4 HANA we activate all business functions in the system. In HANA database these functions need to be activated. We make use of SUM tool for converting the Unicode & then perform Dual Stacks Split; finally use Linux Operating system as it is the best supportive to HANA which gives better performance compared to other Operating system while migrating the tools. We follow certain simple steps for SAP S/4 HANA Migration:

  1. Select S/4 HANA Version:
  2. Choose Mode in which your organization want to run checks
  3. For Online Mode – Results displayed immediately after Checking is over
  4. Background Job – If check will need long running time, use background mode
  5. For Successful conversion to S/4 HANA – start running the simplified items check & fix issues instantly & immediately.
