Table 2: Information on the Cluster Upgrade Utility Page
Upgrading the Cluster
1. Before you start the upgrade, verify that the W-ClearPass 6.4 Upgrade Image is downloaded and available
in the Software Updates portal. If the upgrade image is not available, the Cluster Upgrade Utility page
displays a message advising you to download it.
2. When you open the Cluster Upgrade Tool, it immediately prepares the subscribers for upgrade by
automatically installing the required additional API support. This is a background process and does not
require any actions from the user. A progress indicator is shown during this stage.
To install the patch for API support on the subscriber nodes, subscribers must be able to access the publisher over
HTTP, or they must be able to access the publisher over HTTPS using its hostname and validate the certificate that is
presented (trust the issuer and match the hostname in the certificate CN).
