experience, it is possible to perform in-place migration
from ML2/LXB -> ML2/OVN, albeit with a shutdown or hard
reboot of the instance(s) to complete the VIF plugging and
some other needed operations. I have a very rough outline of
required steps if you’re interested, but they’re geared
towards an openstack-ansible based deployment. I’ll try to
put a writeup together in the next week or two demonstrating
the process in a multi-node environment; the only one I have
done recently was an all-in-one.<o:p></o:p></span></p>

<p>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.<br>
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.<br>
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.</p>
