SAP S/4HANA : On-Premise vs Rise with SAP
If the client wants to move it existing S/4HANA system (as-is) into Rise with SAP environment, SAP has given a five step Brownfield approach which uses the System copy – Backup/Restore method using the migration server. Following are the steps
Step 1: Take the backup of existing S/4HANA system.
Step 2: Move the backup to Object Storage provided by SAP
Step 3: SAP team will move the backup from Object Storage to Storage attached to the HANA Database of the S/4HANA server.
Step 4: Run the SWPM on Migration Server.
Step 5: Restore the backup on the S/4HANA system hosted into Rise with SAP environment.
Since SAP has regulations in place and they do not provide OS/root access on SAP Cloud deployed application and database servers.
Instead of, SAP provided additional VM with full OS/root access and they call it as Migration server. The VM have 128GB RAM, 32vCPUs and 100GB storage which /sapmnt of 20GB and /usr/sap of 80GB.
Steps to provision copy of client system into Rise which is also called as Partner Led Migration
Following details are require from client to start the migration:
