I intend to maintain backport (unofficial) repositories for every
release of Openstack. So, Wheezy for the moment, and I believe,
As for Jessie and the "I" release, it's hard to do forecasts, sorry.

I guess that the thing which is important is to keep your data, more
than the systems. In this case, then the only thing that really maters
is Swift / Glance / Cinder. I don't see how upgrades would break them...
If they do, then this is a bug, and I'll try to address it.
Also, remember that I'm working on these packages so that they go into
production. We (at eNovance) also need smooth upgrades. So I don't think
it is a huge concern.
The only thing is that I will *not* support upgrading from version N to
version N+2. Only from version N to version N+1, and LTS to LTS+1 (eg:
Wheezy to Jessie). And probably, you will have to manually tweak the
configuration files (I don't think that will be so hard though).
