Verification of source system status and infrastructure - analysis of software versions, database disk layout, system status, etc.
Before shutting down the target system
SAP system copies are necessary, regardless of the basic infrastructure. Particularly in the context of automation, preference should be given to solutions that support all relevant types of SAP system operation.
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.
Possibility of manual intervention in case of delta import
Database: For some databases (MS SQL Server) there is the possibility to copy the database files and reattach them on the target system. For the following SAP installation you only have to specify that no SAP loads should be used, but that the database is already there!

A system copy can be created either with SAP transactions (R3trans, from R4.6C SAPinst) or at file and database level. Costs and effort increase with the size of the system and the requirements for availability and data protection. In addition, administrative rework is often necessary, starting with the system name and extending to printers and interfaces.
With "Shortcut for SAP Systems" you get additional functions for the SAP system copy.
Heterogeneous system copy (migration): During the copy, either - the operating system (OS migration) or - the database system (DB migration) or - the operating system and database system (OS/DB migration) are changed.
If no structural changes have been made to the SAP systems involved, the process is even 100% identical.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
