Will this require that the keystonemiddleware is upgraded at the same as the Keystone server across a cloud or at the same time as services such as Nova ?<br>
<br>
Many sites do a component based staged upgrade. This would mean an approach such as upgrading ceilometer or cinder to Liberty significantly before the Nova upgrade with Keystone in the middle.<br>
<br>
- Would the new keystonemiddleware work with the old Keystone version ?<br>
- How would multi-service controllers be upgraded where services such as Nova and cinder controllers share the same server ?<br>
