Verification of source system status and infrastructure - analysis of software versions, database disk layout, system status, etc.
SAP system clone and copy
Unsorted unloading: - By default, R3load sorts table data by primary key before export. This requires time and resources in the source system. Under certain conditions, this sorting can be omitted.
In this context, generated jobs adapt to changes, even if, for example, a DB change, a release change or other changes have taken place. Nevertheless, once created copy jobs can be reused, which minimizes the maintenance effort and a certain susceptibility to errors. This is also the case when switching from one Any DB to another or when moving from an Any DB to Hana.
Before shutting down the target system
Fact: BDLS is a kind of "time eater" for system copies (except when using Hana). An important first step is to integrate the BDLS run into the system copy. Once the copy is effectively through, the BDLS is automatically started.
The task of a system copy created for updates is a carefully integrated system that takes on a specific role in an SAP system landscape. That is why customizing the SAP database of the target system differs significantly from customizing the database of the production system. In a system copy-based update, the database of the target system is completely overwritten with the contents of the production system. Therefore, all SAP-specific customization of the target system must be performed after the update with the system copy. The pre- and post-processing is often performed manually while the target system is running. Specific SAP transactions are used to customize the system. Execution can take a long time and is a source of human error. To automate most transactions, UC4 Automated System Copy for SAP can also be used. Before the update, UC4 Automated System Copy takes care of downloading the required content for the SAP customization from the target system and after the update is complete, uploading the content back to the system.
With "Shortcut for SAP Systems" you get additional functions for the SAP system copy.

This is time-consuming and requires very complex rework.
