You can perform a trial run of a zone migration before the zone is moved to the new machine by using the “no execute” option, -n.
The zoneadm detach subcommand is used with the -n option to generate a manifest on a running zone without actually detaching the zone. The state of the zone on the originating system is not changed. The zoneadm attach subcommand is used with the -n option to read this manifest and verify that the target machine has the correct configuration to host the zone without actually doing an attach.
