You can upgrade an airgap server by using the following two methods:
Applying an incremental package to an existing airgap server
Replacing an existing airgap server with a new airgap server
This section covers the following upgrade paths:
Airgap server upgrade from Telco Cloud Automation 2.1 to 2.3 (Telco Cloud Platform 2.5 to 3.0)
Airgap server from upgrade Telco Cloud Automation 2.2 to 2.3 (Telco Cloud Platform 2.7 to 3.0)
If you are upgrading Telco Cloud Automation from 2.1 to 2.3, note that both Telco Cloud Automation and Tanzu Kubernetes Grid require a sequential upgrade. The airgap server can be upgraded directly from Telco Cloud Automation 2.1 to 2.3. However, this must be done before upgrading Telco Cloud Automation from 2.1 to 2.2.
