<div>There is a difference though between 'simpler for now' and the 'right thing to do',</div>

</div>
<div>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).</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>IMHO bypassing the problem is not a long-term solution (and is not healthy for openstack to even recommend this). </div>
<div><br>
</div>
<div>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 :)</div>

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