Ways of SAP system copy: export / import
System copy of a Unicode system: Source and target system are Unicode systems. The same procedures can be used for the copy, as with the copy of non-Unicode systems.

Post system copy rework - The collected information from the system copy prework is evaluated and the corresponding transport requests are reimported. The development status before the system copy is thus restored. In addition, this package includes a tool that, when individual transports are released, checks whether there are any overlaps on the target system with transports that are still open there. This prevents a transport from unintentionally "overtaking" an earlier released one with the same objects.
SAP SYSTEM COPY - in a nutshell
Strategy as of NetWeaver 2007: Prerequisite: in the case of a Unicode conversion, conversion must be performed during export. If the target database can be built with unsorted unloaded data, all packages are automatically unloaded unsorted. R3load ensures that tables that must always be unloaded sorted are unloaded sorted.

SAP production system copies are created for a variety of reasons, including: - Generating a new non-production system for short- or long-term use - Updating an existing non-production system An SAP system copy is called homogeneous if the source and target operating and database systems are identical. If this is not the case, the system copy is considered heterogeneous. Heterogeneous system copies or platform migrations are not supported by the HP StorageWorks System Copy software for SAP and are therefore not discussed further in this document. In addition, this document deals exclusively with system copies for non-production target systems. Overview of a homogeneous system copy Figure 1 shows copies of an SAP production system that are created for non-production systems. Some copies are short-term (ad hoc) in nature, while others are intended for long-term use. Note that when a long-term system is created from a system copy, a system copy may be needed for updates later in the system's life cycle. This adds the latest transactional data from the original production system. Given their particular importance, this document focuses on scenarios with system copies created for updates. Figure 1: Overview of scenarios with homogeneous SAP system copies Scenario with system copies for updates In order to meet constantly changing business requirements, a production system must be continuously developed and adapted after the initial installation. To do this, you need development, consolidation, and quality assurance (QA) systems that can provide the production system with the appropriate updates as SAP transports.

"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.

This tool provides the ability to create a backup of the database, which can then be used to restore the system.

After the above requirements are met, the target SAP and database instances can be shut down to create the technical system copy for the upgrade.
