</span>We haven't written anything down yet, but here's what I expect.<br>
<br>
Right now we're still changing the db schema however is needed without<br>
messing with versioning. As we get to "production ready", I expect<br>
we'll start being strict about only making backwards compatible ovsdb<br>
schema changes to make upgrades easier.<br>
<br>
There are 2 central components - ovn-northd and ovsdb-server - that<br>
would be upgraded first, which I would expect to be done at the same<br>
time as upgrading your Neutron control plane. As long as any ovsdb<br>
schema changes are backwards compatible, you could do rolling-upgrades<br>
of ovn-controller on compute or network nodes.<br>
