Mirantis OpenStack update from 9.0 to 9.1

Mirantis OpenStack update from 9.0 to 9.1ΒΆ

Mirantis OpenStack 9.1 is distributed as an update repository. Therefore, after you install Mirantis OpenStack 9.0, update it to the version 9.1 using the procedure below.

If you have just installed the Fuel Master node 9.0 and have no running environments yet, update the Fuel Master node to the version 9.1 before creating a new environment.

If you already have an operational Mirantis OpenStack 9.0 environment, detect its customizations using Cudet and Puppet Noop run tools and add these customizations to your updated Mirantis OpenStack 9.1 environment after you complete the update procedure.

Warning

Updating a Mirantis OpenStack deployment results in a downtime of the entire environment. Therefore, before applying the updates to production, you must plan a maintenance window and back up your deployment as well as test the updates on your staging environment. We strongly recommend contacting Mirantis Support if you plan to update your Mirantis OpenStack environment.
