In-place ECC and BW Migrations to SAP HANA at State of Arkansas
Have you considered migrating to SAP HANA or SAP BW/4HANA but are concerned about the challenges you might face in the process? Fortunately, many businesses have successfully made the move and are willing to share how they did it. Case in point, the State of Arkansas recently completed migrations to SAP Suite on HANA and SAP BW/4HANA.
With the help of SAP partners, LSI Consulting and ValueStream, the State of Arkansas performed an on-premise upgrade of its Arkansas Administrative Statewide Information System (AASIS) – including a migration of SAP ECC to SAP Suite on HANA, the migration of SAP BW on Oracle to SAP BW on HANA, and the final conversion to SAP BW/4HANA. All these migration projects were completed in only 6 months. How?
State of Arkansas credits its use of a sandbox approach and a production copy of the system to find 85-90% of the issues with the data, systems and environments in the sandbox before going into development of the new production system. This allowed well-tested migration cutover scripts to be used and repeated across all non-production environments. They used the DMO (SAP Database Migration Option) process to conduct in-place migrations, keeping system IDs intact. And, they established thorough testing procedures and obtained a complete understanding why an issue occurred before proceeding.
According to ValueStream, recommended best practices include:
· Only move the data and objects you really need – every GB of data, and every object not utilized adds time and complexity to the conversion process.
· Execute the sizing program, do your SCI code inspection, and use the transformation finder program to simplify the process.
· The SAP Conversion Guide is your friend – use it!
