Open Stack

Hi,

We are currently preparing to upgrade a kolla-ansible deployed
OpenStack cluster and were wondering if it is possible to upgrade
individual services independently of each other, for example to
upgrade one service at a time to Ussuri while still using 
kolla-ansible to deploy and reconfigure the Train versions of the
other services.

Our idea was that either the Ussuri release of kolla-ansible is used
to deploy Train and Ussuri services (with properly migrated
configuration), or that two different releases and configurations are
used for the two sets of services in the same deployment.

Does anyone have experience if this is practical or even possible?

Thank you in advance,

Erik
