You can update the platform software across the |prod-dc| system by applying
the update strategy for |prod-dc| Update Orchestration.

You can apply the update strategy from the Horizon Web interface or the CLI.
To use the CLI, see :ref:`Update Management for Distributed Cloud

updates to the SystemController / central update repository, create the update
strategy for subclouds, and optionally adjust the configuration settings for
updating nodes. For more information, see :ref:`Update Management for
Distributed Cloud <update-management-for-distributed-cloud>`.
