Overview - Migrating SAP servers between on-premises and IBM Cloud® on IBM Power Virtual Server
Running SAP S/4HANA or SAP ERP 6.0 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
- 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 Migrating SAP S/4HANA by using 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.
Migrating SAP ERP 6.0 on Oracle to IBM Power Virtual Server
Different alternatives to migrate an SAP system on Oracle database are available. The documented solution optimizes Oracle licenses costs and migration efforts. The following steps describe how to migrate an SAP ERP 6.0 Core Component (ECC) System on Oracle.
- Start with the Preparation Steps on Source System section.
- Next, Backup the Source Oracle Database using RMAN.
- Finalize the migration with steps that are described in section Restore the Oracle Database on Target System.
Migrating SAP ERP 6 on IBM Db2 to IBM Power Virtual Server
Multiple options to migrate SAP on IBM Db2 are technically possible. The chapter Migrating SAP ERP 6 on IBM Db2 to IBM Power Virtual Server describes these two major options:
- Migration option 1 - Back up and restore is the easier migration option with downtime during the complete migration
- Migration option 2 - IBM Db2 high availability and disaster recovery (HADR) is a downtime-optimized version, more complex but with minimum downtime.
