Technical system copy for the upgrade
SAP Landscape Copies
Different DDLORA* files can be assigned to the R3load packages. The assignment is done by a text file, which is given to the MigrationMonitor as parameter 'ddlMap = mapDDL.txt' and evaluated by it.
Companies with backup systems can use these for a client copy and thus save on the computing power of the productive system. However, the burden of copying falls on the SAN. Because the reliability is limited by the misuse of the backup system and the storage network is additionally burdened, users should keep the runtime of this refresh variant as short as possible.
Downtime
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.
"The creation of SAP system copies used to represent an enormous effort," says Martin Schulz from SAP Basis Administration. Almost 4,000 employees worldwide access our SAP systems directly. If the SAP systems are down, then nothing works in many departments - and that certainly happened in the past. Although the actual copying process is completed in just a few hours, the manual post-processing - which includes, for example, adjusting parameters, users and rights, profiles, system settings and interfaces - can take up to a week. This keeps the entire seven-person SAP Basis team busy.
SAP system copy is made much easier by the "Shortcut for SAP Systems" application.
Instead of several days, only hours are required for system copying.
For example, it is automatically recognized whether the system is an Abap, Java or double-stack system.
