This document describes how to upgrade Cisco Identity Services Engine (ISE) software on Cisco ISE appliances and virtual machines to Release 2.1.
Upgrading a Cisco ISE
deployment is a multi-step process and must be performed in the order specified
in this document. Use the time estimates provided in this document to plan for
upgrade with minimum downtime. For a deployment with multiple PSNs that are
part of a PSN group, there would be no downtime. If there are endpoints
authenticating through a PSN that is being upgraded, the request is processed
by another PSN in the node group. The endpoint is re-authenticated and granted
network access after successful authentication.
If you have a
standalone deployment or a deployment with a single PSN, you might experience a
downtime for all authentications when the PSN is being upgraded.
You can directly upgrade to Release 2.1, from any of the following releases:
Cisco ISE, Release 1.3
Cisco ISE, Release 1.4
Cisco ISE, Release 2.0
Cisco ISE, Release 2.0.1
If you are on a version earlier than Cisco ISE, Release 1.3, you must first upgrade to one of the releases listed above and then upgrade to Release 2.1.
You can download the upgrade bundle from Cisco.com. The following upgrade bundles are available for Release 2.1:
ise-upgradebundle-1.3.x-and-1.4.x-to-2.1.0.x.x86_64.tar.gz—Use this bundle to upgrade from Release 1.3 or 1.4 to 2.1
ise-upgradebundle-2.0.x-to-2.1.0.x.SPA.x86_64.tar.gz—Use this bundle to upgrade from Release 2.0 to 2.1
This release of Cisco
ISE supports both GUI-based as well as CLI-based upgrade.
The GUI-based upgrade from the Admin portal is supported only if you are currently on Release 2.0 or later and want to upgrade to Release 2.1. See Upgrade a Cisco ISE Deployment from the GUI for more information.
From the Cisco ISE CLI, you can upgrade from Release 1.3, 1.4, or 2.0 directly to Release 2.1. See Upgrade a Cisco ISE Deployment from the CLI for more information.
For a list of known upgrade-related caveats, see the Release Notes for Cisco Identity Services Engine, Release 2.1.
