Configuration parameters are associated with virtual machines in the migrated vApp , including network segments (vApp networks) that are private to the vApp itself in the source vCloud. Some of these configuration items are maintained during a migration, while others require reconfiguration by the vApp user after migration.

vApp networks are not maintained across a vCloud migration—vApp networks that are defined in a vApp in vCloud A are not created and mapped to the virtual machines within the vApp in vCloud B. Assuming that vCloud A and vCloud B use the same network topology, after moving the application to vCloud B, the end user must complete the configuration process by recreating the vApp networks as they were defined in vCloud A.
