Upgrade zone attach/detach

Since the Solaris 10 5/08 Operating System (Solaris 10 5/08 s10s_u5wos_10 SPARC ==> 10_u5), system administrators have had the ability to detach and attach zones, that is, detach a zone from one system and attach it to another. Some restrictions applied with the initial functionality, in that the source and destination system where the non-global zone was being attached had to have the same software level in terms of package versions, patch levels, and architecture. In other words you couldn't move a zone from a sun4v system to a sun4u system or from a prior Solaris release to the current Solaris update release but later updates this is possible now.

In the Solaris 10 10/08 release (Solaris 10 10/08 s10s_u6wos_07b SPARC ==> 10_u6), new functionality was provided by way of the "update on attach" command, the -u argument to zoneadm attach.
