Shutting Down the Target System
Automatic determination of delta states after SAP system copy/recovery
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).
Another method of creating an SAP system copy is to use external tools such as Oracle RMAN or Microsoft SQL Server Backup. These tools allow you to create a complete copy of the database as well as a copy of the file system. However, it is important to note that special knowledge is required when using these tools to ensure that the backup is created correctly.
Hybrid: for example, the source systems on-premises and the target systems on cloud
In advanced SAP systems, there are also methods such as system cloning, which allows an exact copy of a production system to be created and used as a test system. These methods save time and effort in creating system copies and allow companies to make their IT processes faster and more efficient.
One of the most common methods of creating an SAP system copy is to use SAP's own tool "BR*Tools". This tool provides the ability to create a backup of the database, which can then be used to restore the system. It can also be used to export certain data from the database and import it into another system.
The tool "Shortcut for SAP Systems" is excellently suited to complete an SAP system copy easier and faster.
The export files are copied to the prepared target system and imported again during the SAP installation with SUM.
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP. This includes the maintenance of different services related to database, operating system, application and web servers in SAP system landscape and stopping and starting the system.

In order to check whether the usable settings are correctly adjusted, especially in the case of large databases, the runtimes are automatically logged during the BDLS.
