1 Prerequisites
1.1 Run FULL online backup in Source system before export and also backup File system of source system before export.

1.4

Processing Steps of a System Copy (Oracle only)

With the settings in the property file listed in the examples above and an Oracle database as source and target database, the following prerequisites must be fulfilled:

The following directories must exist on the export host (parameter: exportDirs):

\temp\export_dump\ABAP\DATA

\temp\export_dump\ABAP\DB

\temp\export_dump\ABAP\DB\ORA

The \temp\export_dump\ABAP\DATA directory must contain the STR files generated by R3ldctl.

The \temp\export_dump\ABAP\DB directory must contain the DDL<DBTYPE>.TPL files generated by R3ldctl.

The \temp\export_dump\ABAP\DB\ORA directory must contain the EXT files generated by R3szchk.
