Homogeneous and Heterogeneous System Copy for SAP Systems Based on SAP Web Application Server ABAP 6.40 SR1
When a homogeneous system copy is performed, the target SAP system is installed on the same operating system and the same database system as the source SAP system. The contents of the database are copied from the source to the target system. During a heterogeneous system copy, the operating system or the database system is changed. Migration is a synonym for heterogeneous system copy.
