Charmed OpenStack Upgrader (COU) is an application (packaged as a snap) to upgrade a Canonical distribution of Charmed OpenStack in an automated and frictionless manner. The application detects the version of the running cloud and proposes an upgrade plan to the next available OpenStack release.

COU follows the steps defined in the charm-guide upgrades overview.

Notes:

• Currently only control plane upgrades are supported.

• The tool supports upgrades from focal-ussuri to focal-yoga.
