Test and training system: data anomyization, migration of master data, migration of user data / passwords
Verification of source system status and infrastructure - analysis of software versions, database disk layout, system status, etc.

This procedure is currently gaining in relevance, as it is required for the migration from SAP ERP to S/4HANA. If the current system runs on Windows Server and SQL Server or Oracle, the target system must now run on Linux and SAP Hana.
After shutting down the target system, the technical system copy for upgrade 1 can be created at the infrastructure level. To automate the creation of the technical system copy for upgrade, HP System Copy can be used for the following steps.
Applicability of Systemcopy as a Service
Suitable tools make it possible to automate and accelerate the necessary creation of true-to-original SAP system copies, for example. This means that you have all production data available on your test system in a short time.
An alternative to this is a refresh using a client copy. The test environment will then be missing audit documents, among other things, but the development objects will remain untouched. The client copy only works from a running SAP system, but it burdens the system with database queries and transfers data more slowly than a system copy. The affected client is not available during the copy process. Since there are no options within the client to select what all should be copied, the runtime is often unacceptable.
With "Shortcut for SAP Systems" you get additional functions for the SAP system copy.
