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. 2013/10/31 Jesse Pretorius <jesse.pretor...@gmail.com> > Hi everyone, > > Migrations from Essex to Grizzly/Havana are starting to hit my radar of > responsible tasks and I'm disappointed that beyond this old wiki note [1] > and a wealth of questions with very few answers [2], there is very little > available to support the migrations from what used to be part of nova to > the newer full projects. > > I really think that as Openstack grows and the projects split out, one of > the focal areas really needs to be on ensuring that people using the older > versions can migrate to the newer versions without needing to do all sorts > of terrible hacks. > > Issues at hand, for now, are: > > 1) Migrating from nova-volume to cinder > 2) Migrating from nova-network to neutron > > It'd be great if we could pool efforts to figure out an effective way of > handling these migrations.
