Migrating a Non-Global Zone From One Machine to Another

The zonecfg and zoneadm commands have been modified to enable you to migrate a non-global zone from one system to another. The procedure used detaches a halted zone from its current location, and attaches the zone at a new location. The global zone on the target system must be running the following:

The zone detach process creates the information necessary to attach the zone on a different system. The zone attach process verifies that the new machine has the correct configuration to host the zone. You can make the zonepath available on the new host in several ways. Therefore, the actual movement of the zonepath from one system to another is a manual process that is performed by the zone administrator.

When attached to the new system, the zone is in the installed state.
