Introduction
This section provides instructions for upgrading a W-ClearPass cluster using the Cluster Upgrade Tool.
The Cluster Upgrade Tool is a simple user interface that automates the upgrade procedure for a W-ClearPass
cluster. When the Upgrade is initiated, no manual actions are required until the Publisher and all selected
Subscribers have been upgraded.
This release of the tool can be used to upgrade W-ClearPass 6.3.6, 6.4.7, 6.5.x, and 6.6.x systems to
W-ClearPass 6.6. It cannot be used to upgrade to an earlier version of the Cluster Upgrade Tool.
If you have an earlier version of the Cluster Upgrade Tool already installed, you can install this version directly
over the earlier version of the tool; no cleanup steps are needed.
Cluster Upgrade Process Overview
These tasks summarize the Cluster Upgrade process:
1. Download the upgrade image to the Software Updates Portal.
2. Install the Cluster Upgrade Tool (see Installing the Cluster Upgrade Tool).
3. Launch the Cluster Upgrade Tool and specify the Subscriber nodes to be upgraded (see Launching the
Cluster Upgrade Tool).
4. Initiate the Upgrade procedure (see Upgrading the W-ClearPass Cluster).
The Cluster Upgrade tool automatically performs the upgrade.
5. After the upgrade, verify that the Publisher and all Subscriber nodes in the cluster are back in sync and all
services are accessible (see Viewing Upgrade Status).
Cloning a virtual machine to facilitate a W-ClearPass deployment is not recommended or supported.
Before You Upgrade
Before you begin the cluster upgrade process, ensure that the following tasks have been completed:
1. Review this section and the latest Release Notes for W-ClearPass 6.6.
2. Plan for adequate downtime for the upgrade.
Use the upgrade time estimates in Sample Times Required for Upgrade on page 728 as a guide.
3. Install the Cluster Upgrade Tool on the Publisher node of your 6.3.6, 6.4.7, 6.5.x, and 6.6.x version.
4. Before installing the Cluster Upgrade Tool on the Publisher, verify that W-ClearPass services are up and
running on both the Publisher and all Subscriber nodes. Verify again after installing the tool.
5. If the cluster password contains special characters, change it temporarily to only use alphanumeric
characters (letters and numbers) before installing this patch.
You can change the cluster password back to the old password after the cluster upgrade completes.
6. HTTP, HTTPS, and SSH port traffic must be allowed between the cluster nodes. This is required in order for
the tool to be able to communicate between nodes.
Verify that the following ports are in an open state between the cluster nodes:
n Port 80 (HTTP)
