Thanks for replying, I'd really love to see your outline / list of 
steps. BTW, we are actively working on switching to openstack-ansible - 
so that would suit us well.
We also came to the conclusion that a shutdown of all instances might be 
required. Question is, if that has to happen instantly or if one could 
do that on a project by project base.
Our cloud is small enough to still make this feasible, but I suppose 
this topic is or will become more important  to other, larger clouds as 
well.


Regards


Christian
