SAP Migration Cockpit is a tool that allows you to migrate data from the current system (whether it is SAP or not) to the new S/4HANA system. This article explains how to migrate data with the SAP Migration Cockpit between a system and S/4HANA by reading the data directly from the current SAP system.
To migrate your data with SAP Migration Cockpit you need to access the application Fiori Migrate your data and follow the steps below:
In the Migrate your data app select Create > Migrate data directly from SAP System

Here, you specify general information for your project. Note that it isn’t possible to change the scenario after you’ve created the project.
Provide a name for the project, a scenario, and the source system. Then click on Step 2:

It isn’t possible to change the development package after you’ve created the project. Note that if you use a local development package, you cannot transport the project to another system.
Data selection
The Migration Cockpit uses organizational units such as company codes to select data from the source system. These organizational units are predefined for each scenario. For example, the scenario SAP ERP to SAP S/4HANA uses company codes to select data from the source system.
Only data that is relevant for the specified organizational units will be selected from the source system.
