Upgrade Overview

This section covers upgrading a Private Cloud Director environment — preparing your hosts, sequencing the upgrade safely, and verifying that every service is healthy afterward.

Private Cloud Director supports two deployment models:

• SaaS — Platform9 hosts and operates the management plane.

• Self-Hosted — you operate the management plane on-premise.

The runbooks below apply to both models. Steps that are specific to the on-premise (Self-Hosted) management plane — primarily the airctl commands — are called out separately within each runbook.

In this section

• Host Upgrade Runbook — pre-upgrade environment checks, host upgrade ordering across multi-role hosts, Ubuntu 22.04-to-24.04 OS upgrade caveats, and failure recovery.

• Post-Upgrade Verification — the checklist to confirm region health, host roles, GPU, storage, and networking are healthy, then re-enable VM HA and DRR.
