Solaris 10 5/08: About Validating an lx Branded 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.
