I agree its not simple (from experience),
There is a difference though between 'simpler for now' and the 'right thing to
do',
If software doesn't support the right thing to do ('upgrade', 'dist-upgrade' -
or yum equivalent) then the community needs to make that work (and stop with
new features).
Otherwise the community is in a whole world of trouble. If openstack is to make
the life of operations & other people better and the only way to operate it is
to build new regions, then something feels backwards in this equation.
IMHO bypassing the problem is not a long-term solution (and is not healthy for
openstack to even recommend this).
I don't even think its a short-term solution honestly since building a new
region costs $$ and downtime. Who wants to do that every 6 months, I can surely
tell u I don't :)

Subject: Re: [Openstack] Migrate instances/tenants between clouds
I do not even want to try to upgrade my system...
I know that DPKG is awesome and handle system upgrades carefully but, sounds
more simpler to just build a new Region...
This doesn't sound trivial (like `apt-get update ; apt-get dist-upgrade`):

Don't you think!?

Whatever happened to doing in-place upgrades?
Has that been problematic for u, are people just not doing it? If they are
avoiding it, why?
Shouldn't just going from folsom->havana work, if not, why not; it worries
me that this isn't priority #0 if it doesn't work.
