7.8.2. Upgrade command overview
The upgrade process involves different commands that you run at certain stages of the process.
This section only contains information about each command. You must run these commands in a specific order and provide options specific to your overcloud. Wait until you receive instructions to run these commands at the appropriate step.
7.8.2.1. openstack overcloud upgrade prepare
This command performs the initial preparation steps for the overcloud upgrade, which includes replacing the current overcloud plan on the undercloud with the new OpenStack Platform 17.1 overcloud plan and your updated environment files. This command functions similar to the openstack overcloud deploy command and uses many of the same options.
Before you run the openstack overcloud upgrade prepare command, you must perform the overcloud adoption. For more information about overcloud adoption, see Performing the overcloud adoption and preparation.
