In different situations during the life-cycle of your SAP solution, it may be appropriate for you to perform a system copy or a migration.

If you want to change your operating system, your database, or both, you must perform a system copy. SAP also recommends that you perform a system copy if you are planning to set up a test system, demo system, or training system.

As of SAP 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.

Note Note

When you perform a system copy, all usage types in the source system are copied to the target system. This means that you cannot leave out any usage types in the source system or copy selectively to a target system.

End of the note.
Definition of Terms

  • 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.

  • 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.
