Overview - Migrating SAP servers between on-premises and IBM Cloud® on IBM Power Virtual Server
Running SAP S/4HANA or SAP ECC on IBM IBM® Power® Virtual Server in a hybrid cloud environment offers:
- A flexible infrastructure
- Consistent platform for SAP HANA based and traditional applications
- Best-in-class performance and
- Freedom to run SAP workload where you need it.
Use the following information to understand how to migrate an SAP system between on-premises and Power Virtual Server.
SAP workload-related hybrid cloud network considerations
The hybrid cloud network connection is the base decision for all migration scenarios.
Deciding on the network connection option and estimating bandwidth requirements are the first steps. A typical SAP database size can be huge. The network connection must be able to complete intersite data replication in sufficient time. Read the Hybrid Cloud Network Considerations for SAP applications on IBM® Power® Virtual Server section for details.
Migrating SAP S/4HANA to IBM Power Virtual Server
Multiple options to migrate SAP S/4HANA between sites are possible. The following solution reduces SAP application downtime by using SAP HANA System Replication (HSR):
- Check the SAP S/4HANA Pre-Migration Steps section.
- Install and prepare a target system in Power Virtual Server as described in the Creating the Target SAP HANA System on IBM Power Systems Virtual Servers pre-step section.
- Migrate the application data according to SAP HANA System Replication.
- Perform an SAP HANA System Replication Takeover to activate services on the target site and make sure that clients connect to the new location.
