Hybrid: for example, the source systems on-premises and the target systems on cloud
Food for thought for another productive system: until when must the system be identical, keyword: transaction log
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. Based on these results, it is possible to analyze how the runtime can be further optimized. By the way, BDLS reports and optimization options are displayed in the BSC GUI, including modification options.
In practice, customers have either built their own tools to make the appropriate configurations, or there are extensive lists of steps to be processed manually. This approach is time-consuming and error-prone.

A SAN enables a system copy during dialog operation. In this way, virtual copies of a logical volume, so-called snapshots, can be created. Data is only copied if it is changed in the original data volume (copy-on-write procedure). When copying from a snapshot to file level, the affected systems remain available. However, this procedure puts a strain on the storage network. If this takes several days, the response times of the productive system deteriorate.
"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.
The assignment is done by a text file, which is given to the MigrationMonitor as parameter 'ddlMap = mapDDL.txt' and evaluated by it.
Instead of several days, only hours are required for system copying.
