Upgrading Solaris zone to solaris 11

We have solaris zones running in [Sparc T5](https://blogs.oracle.com/orasysat/the-sparc-t5-servers-have-landed) server Currently a solaris zone run Solaris 10 OS version. $uname -a SunOS zone01 5.10 Generic_150400-30 sun4v sparc sun4v Going further, we would like this zone to run Solaris 11 OS version, because Solaris 10 OS is going End of Support. ------------------------------------- Critical goal is: We do not want to build new solaris zones(Solaris OS 11) at any cost. We want existing zones to get upgraded to Solaris 11. Why do we use these zones? Because we have a business application running on it, which is the actual usage scenario. My understanding for upgrade of zone is, shut down all solaris zones and upgrade Sparc T5 server(not solaris zone) from solaris 10 to solaris 11. Start solaris zones after upgrade of Sparc T5 server. What is the recommended approach to upgrade an OS of an existing solaris zone? Edit: I read that: "We can simply detach a Zone from one Global Zone (OS) and attach it to another Global Zone on another machine along with the application." Can't a solaris 10 zone be migrated from version 10 global zone to version 11 global zone? And then upgrade the migrated zone...
