Cisco ACI Upgrade Guide
The APIC controller is a distributed software application that runs on a redundant pair of physical servers. The APIC software is deployed in a clustered configuration and uses an embedded database.
The Cisco ACI fabric is upgraded using a three-step process that is initiated from the APIC GUI or REST API. The upgrade process is designed to be non-disruptive and can be performed while the fabric is in production.
The first step in the upgrade process is to download the software upgrade file from Cisco.com. The file is then uploaded to the APIC using the GUI or REST API.
The second step is to stage the software upgrade on the APIC. During this step, the APIC validates the upgrade file and prepares the cluster for the upgrade.
The final step is to apply the software upgrade to the APIC cluster. During this step, the APIC installs the software upgrade on the active controller and reboots the standby controller. After the standby controller is rebooted, the APIC switches to the upgraded software version.
The entire upgrade process takes approximately 30 minutes to complete.

The Cisco Application Policy Infrastructure Controller (APIC) is the central point of management, policy, and orchestration for the Cisco ACI fabric. The APIC provides an intuitive graphical user interface (GUI), a comprehensive REST API, and powerful tools for monitoring and troubleshooting the Cisco ACI fabric.
