Add to MyDocs | Hide Show Table of Contents

Introduction

This document describes the steps required to perform a zero downtime upgrade of a PingAccess cluster to version 5.0 or higher. A zero downtime upgrade allows you to upgrade your environment with no impact to resource availability or existing user sessions.

Though this procedure is applicable to any PingAccess cluster upgrade to version 5.0 or higher, there are minor variations depending on your PingAccess source version. Those variations are clearly described where applicable.

Note that there are some steps, particularly those related to working with a load balancer, that are dependent on your environment. It is expected that you are familiar with the tasks required by these steps and, accordingly, this document does not attempt to offer detailed instruction on performing these tasks.

Important: In order to achieve a successful upgrade, perform the steps in this document in the order that they are presented. Deviation from these steps may result in a failed upgrade and/or system downtime.

To begin the upgrade process, Disable key rolling to prevent active sessions from being invalidated.
