  Solaris 10 5/08: About Validating a Zone Migration Before the
Migration Is Performed  You can perform a trial run 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 zone manifest is sent to stdout. The
global administrator can direct this output to a file or pipe it
to a remote command to be immediately validated on the target
host. 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.  The zone on the target system does not have to be
configured on the new host before doing a trial-run attach.
