Overall Solution

In this scenario, there are five servers, four of which are used to deploy applications and one is used to deploy database. The operating system (OS) of both the source and target systems needs to be the same. The HANA database version of the target system must be no earlier than that of the source system. The architecture and migration solution are shown in the following figure:

1. Use HUAWEI CLOUD Server Migration Service (SMS) to completely replicate and migrate the system image and disk data of the four application servers and the mounted storage disk to the target system.

2. Use the SFS shared storage and the tar and scp commands of the OS to copy data in the SAP directory to the target system.

3. Use SAP HANA System Replication (SR) to replicate data in HANA database to the target database.
