SAP S/4HANA Migration Cockpit is a web-based tool to migrate your legacy data in SAP. This tool is available from SAP S/4HANA 1610 onward. It allows to download predefined  Excel based Templates (Excel XML) which enables you to easily extract legacy data in these templates and upload. Migration Cockpit uses BAPI functionality to transfer/upload data in target system.


Migration objects are defined by SAP, and describe how to migrate data from legacy system to SAP S/4HANA i.e. which tables are needed and the relationships between the tables etc. Material Master, Customer Master, Sales Order, Purchase Order etc. are migration objects in Migration Cockpit and SAP provides an Excel based template for each migration object.

Transaction Code
