Ways of SAP system copy: export / import
The system copy
Different DDLORA* files can be assigned to the R3load packages. The assignment is done by a text file, which is given to the MigrationMonitor as parameter 'ddlMap = mapDDL.txt' and evaluated by it.

"Shortcut for SAP Systems" offers the possibility to backup and restore any tables. Not only those that are considered in the PCA tool (Post Copy Automation) but also self-developed tables. Thanks to the simple and clear interface, backup and restore of self-developed tables can be integrated quickly and easily. The command line interface can also be used to automate the process: for example, a simple line command can be used to perform a complete backup of table contents before the system copy, and a simple line command can also be used to restore these tables after the system copy. This means that the complete backup or restore process can be integrated into any automation software.
