Clustering Solaris Zones/Containers
Hello everyone. I'm working on a fairly large project at my company and have been looking for some guidance. I just happened to stumble on this forum when looking for help with Solaris, so I'm hoping that you all won't mind me bothering you with my questions. 
Anyway, here goes. Is it possible to cluster an application within Solaris 10 Zones/Containers so that we could fail an application and all of its filesystems from one container to another? We are currently using VCS (though would consider other clustering technologies) and their recommendation is to have 2 separate, but identical zones configured on the hosts. This allows you to patch the offline one while the other one runs production. But, I can't seem to find a way to migrate the app from one zone to another for failover. Is this possible or in this scenario is it necessary to also maintain 2 distinct copies of your app, configuration and log files?
