Hybrid: for example, the source systems on-premises and the target systems on cloud
SAP system deployment scenarios
Preparation before system copy - All information about transport requests that should be re-imported on the target system of the system copy is evaluated and collected: Already released transport requests that have not yet landed on production. Open transport requests that should survive the system copy (maintain development status). The respective owners of the transports have the possibility to discard an obsolete development.
You should also create a delta list for all transports that have not yet reached the production system. Software contained in open transports is lost during the upgrade, which may seem useful for cleaning up the system, but can have dire consequences for development projects. That's why you should take a close look at delta transport lists before proceeding with the upgrade. UC4 Automated System Copy allows you to automate the above steps. If necessary, you can add additional steps without losing testing capabilities.
Possibility of manual intervention in case of delta import
A non-production SAP system should also have the same repository status as the source system, regardless of the data transfer method chosen for the refresh. All the data that makes up an SAP system is stored in the repository. This includes, among other things, the definitions for the database fields and tables for master and transaction data.
Even if the target system is not used for production in an update scenario based on a system copy, it is of central importance for developers and thus also the software lifecycle of the production system. That's why you should avoid upgrade downtime in both the production source system and the non-production target system. Production system downtime depends primarily on the method you use to create the image of the production data to be used in the target system. This image must be a transferable database image - for example, a database export, a backup copy, or an array-based reconciliation. To eliminate downtime in the production system and minimize the impact on application performance-regardless of the size of the production data reconciliation-you can use, for example, HP StorageWorks System Copy for SAP (HP System Copy), which has a disk array-based replication capability. Downtime in the target system depends on the following factors, among others: The time required to restore production data reconciliation in the target system The amount of pre- and post-processing in the target system With HP System Copy, images of production data can be created in minutes, with each step between shutdown and reboot of the target system occurring automatically. However, after the reboot, the target system is not immediately ready for use, as additional steps must first be performed (see description below).
With "Shortcut for SAP Systems", tasks in the area of SAP system copy are simplified and made possible.
Ideally, a tool for creating SAP system copies should take the following core copy processes into account: Check and pre-processing, restore, actual execution, and post-processing.
The tables to be copied can only be determined on the basis of the date.
