uuid and cloned zone = ops center confused

I've used the zone clone approach to build out a development system then snapshot and clone it, from the command line, to make a production zone as well.

Sometimes both are on the same global, sometimes not. Ops Center would discover one then it would think the second is the same name.  I could not understand why until  I looked into the zonecfg XML where I found that both original and clone have the same image uuid. They're different configured systems, separate hostname and IP.

Ops center is using the uuid to distinguish among zones. That's not unreasonable but it conflicts with the result of a by-the-book zone clone that gives me two zones with the same uuid. So I suppose I need to change the uuid of the cloned zone not sure how to do this safely.
