I've come across the two terms data transfer and data migration with very close meaning.
Request you to define these terms as applied in SAP.
If there is no difference, they must be used interchangeably with the same meaning.
As a functional consultant, my understanding is that when data comes into an SAP system from any non-SAP system,then it is data migration. And I'm not sure if data transfer is conceptually different from this.
Thank you very much.
