Test and training system: data anomyization, migration of master data, migration of user data / passwords
Pre- and post-processing
The steps to be taken before shutting down the target SAP system can be summarized as follows: Well before performing the upgrade, inform the target system users - especially project managers, developers, and testers - about the planned maintenance work via e-mail, SAP system messages, and/or a message at the system logon. Using the SAP transport system requires careful preparation so that software development projects can be completed as far as possible. Shortly before the start of the update, inform users again that maintenance work on the system is imminent and that they should log off from the target system. After logging users off and locking them out, download system-specific content from the target system database for customization (including security settings, Remote Function Call (RFC) targets, and operating modes).
Acceleration/table export: up to 4 times faster. The larger the table and the higher the effort for sorting, the greater the time gain during export.
To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.
Ways of SAP system copy: export / import
Packages that have not been explicitly assigned a special DDLORA file receive the DDL file specified via the "ddlFile=" parameter. The default is DDLORA.TPL.
One to two pre-tests are required, one of which should be performed on the production system. The additional load on the production system caused by the IMIG has been negligible. Split/mirror techniques allow many actions to be moved from the production machine to another machine.
Tools such as "Shortcut for SAP Systems" are extremely useful in SAP system copy.
Technically, it is quite possible to build up a degree of automation here as well, but officially certified consultants ("migration consultants") are required to perform the heterogeneous system copy.

Effort decreases from 1st test to 2nd test to final copy.
