1 Symptoms: 1 At several stages in the lifecycle of your SAP solution, you will face the requirement to perform
a system copy or a migration. For example, SAP recommends that you perform a system copy to create test, demo and training systems. Also, if you need to change your operating system and/or database, you have to perform a migration of your SAP system.
2 Up until NetWeaver 04 (SAP Web Application Server 6.40), it was only possible for you to
perform a system copy for an ABAP system.
3 As of NetWeaver 04 SR1 (SAP Web Application Server 6.40 SR1), you also have the option of
performing a system copy for a Java add-in of an ABAP system, as well as for a Java standalone system.
4 As of NetWeaver 7.0, you can copy a mixed ABAP Stack and Java Stack system in a single
operation, not just standalone ABAP or Java systems.
5 When you perform a system copy, all software units or usage types in the source system are
copied to the target system. This means that none of the usage types in the target system can be excluded from the system copy, nor can you select usage types.
6 You perform a homogeneous system copy if your target system is on the same operating
system and database system as your source system. The database contents are copied from the source system to the target system.
7 You perform a heterogeneous system copy if you want to change the operating system or
database system. Migration is another term for a heterogeneous system copy.
