You can also manage identical systems (same SAPSYSTEMNAME and same host names) or cloned systems. For each system (also the source system), you must maintain the profile parameter system/uuid. SAP Landscape Management can contact each application instance of the source as well as the cloned system using a unique host name which might be a fully qualified domain name and IP address activated on the host. The SAP Landscape Management software can manage application instances and hosts using fully qualified domain names.
