Open Stack

Yes, OS as big product tries to split hierarchy of responsibilities.
Currently we have serveral tasks, i suppose.
First one is upgrading from one stable release to another.
Second one is migrating from one release to another.

Currently OpenStack has several deployment projects: TripleO, Fuel (<--- is
a bit different from TripleO, it performs bare-metal deployment of whole
OS).

As way of covering issue of upgrading/migrating, personaly i see, we could
suggest those projects to propose a way of solving it.
