Refreshing a System

You refresh a system to overwrite an existing target system with the latest data from a source system while maintaining the configuration.

Prerequisites

The general prerequisites for provisioning systems have been met.

For more information, see General Prerequisites for Provisioning Systems.
The system can be used for copying. You have configured the initial entities.
Recommendation
- For storage-based systems:
  
  Mount points containing the database logs, data, and software are configured only for the database instance and must not be shared with any other instances of the system.
  
  Install the database client software on a separate volume if it is needed by the SAP application servers.
- For virtualization-based systems:
  
  The database is installed on a separate virtual machine.
For more information, see Initial entities.
To execute SAP TDMS standalone data scrambling during the system refresh, you have configured SAP Test Data Migration Server.

For more information, see Configuring SAP Test Data Migration Server.
You have configured your infrastructure.

For more information, see System refresh setup procedure.
The source system is on a different server than the target system.
You have generated an XML backup data file containing all SAP Landscape Management configuration details for this system so that you can restore your configuration settings.

For more information, see Exporting the Configuration Data.

System Refresh

You refresh a system to overwrite an existing target system with the latest data from a source system while maintaining the configuration.

ABAP systems

To prevent overwriting target system configuration, SAP Landscape Management exports the target system tables that contain configuration information before starting the system copy. After the ABAP system copy has finished, SAP Landscape Management imports the configuration information into the target system.
Java systems

To prevent overwriting the target system configuration, you use the Java post-copy configuration wizard to export target system tables that contain configuration information before starting the system copy. After the Java system copy has finished, you use the Java post-copy wizard to import the configuration information into the target system.
