Migrating Solaris 10 Zones to new machine.

How do you migrate a system with one global zone and two non-global zones to a new but similar machine?

AFAIK you can't move global zones, so for the global you have to do a fresh install on the new one then transfer config files etc.

For non-global zones, (1) halt zone (2) zoneadm detach zone (3) move data (rsync as root for best results) (4) create new zone config (5) zoneadm attach zone to data (6) boot zone. I've done this once, and you can Google for more details.

Thanks@AlucardZero!

I wish there is a way to get a global zone to a new machine.
The reason for that is because all non-global zones sit on top of global zone and share the same kernel with it.

Is there a way to snapshot it or back it up or ..?

Thanks a lot

That depends on what you mean by "similar machines". If the machines are close enough, you might just move the disks (physically or logically) from one to another and you have migrated all your zones, including the global one. Of course, there might be some things to fix / adapt for this to succeed.
Alternatively, flash archives are a way to clone a global zone to other machines.
