Verification of source system status and infrastructure - analysis of software versions, database disk layout, system status, etc.
Before shutting down the target system
SAP offers its own solution for this: With the Test Data Migration Server (TDMS), individual tables can be selected and written indirectly, via a third SAP system, from the source to the target system via Remote Function Call (RFC). However, the selection of business objects is not possible in the standard system. The tables to be copied can only be determined on the basis of the date. The content restriction applies from a certain point in time. At least the SAP tool can be used to reduce the runtime of an extraction of test data compared to the system copy or client copy.
SAP environments can quickly become time-consuming. For example, when it comes to creating system copies of a production environment on the test and quality assurance (QA) system. Because of the time required, some QA systems turn out to be outdated and thus even ticking time bombs. A software tool from Libelle now makes it easier to update QA systems in SAP architectures on System i as well.
Purpose of the SAP system copy
The initial screen will then, for example, already show an overview of the - in some cases automatically - integrated systems and their status, as well as system information such as release, patch level and the like. The use of a comprehensive dashboard will then also be included.
Over 30 productive systems at more than 9 customers successfully copied using IMIG. For the Unicode conversion of a 4.5 TB system (2.7 TB data) a downtime of 16 hours was achieved (including the follow-up work such as reconfiguration, updating DB statistics, generating reports, creating backups, testing the system).
SAP system copy is made much easier by the "Shortcut for SAP Systems" application.
This often leads to special challenges due to a lack of resources or capacities.
To do this, you need development, consolidation, and quality assurance (QA) systems that can provide the appropriate updates to the production system as SAP transports.
