Prerequisites for Upgrading Your ACE

Prerequisites for Upgrading Your ACE
Before you upgrade your ACE software, please read this appendix in its entirety so that you fully
understand the entire upgrade process. Please be sure that your ACE configurations meet the upgrade
prerequisites in the following sections:

Changing the Admin Password

Before you upgrade to software version A2(1.1) or higher, you must change the default Admin password
if you have not already done so. Otherwise, after you upgrade the ACE software, you will be able to log
in to the ACE only through the console port. For details about changing the Admin password, see
Chapter 1, Setting Up the

Changing the www User Password

Before you upgrade your software version, you must change the default www user password if you have
not already done so. Otherwise, after you upgrade the ACE software, the www user will be disabled and
you will not be able to use Extensible Markup Language (XML) to remotely configure an ACE until you
change the default www user password. For details about changing the www user password, see Chapter
2, Configuring Virtualization in the Cisco 4700 Series Application Control Engine Appliance
Virtualization Configuration Guide. In this case, the username would be www.

Checking Your Configuration for FT Priority and Preempt

If you want the currently active ACE to remain active after the software upgrade, be sure that the active
ACE has a higher priority than the standby (peer) ACE and that the preempt command is configured. To
check the redundant configuration of your ACEs, use the show running-config ft command. Note that
the preempt command is enabled by default and does not appear in the running-config.

Creating a Checkpoint

We strongly recommend that you create a checkpoint in the running-configuration file of each context
in your ACE. A checkpoint creates a snapshot of your configuration that you can later roll back to in
case a problem occurs with an upgrade and you want to downgrade the software to a previous release.
Use the checkpoint create command in Exec mode in each context for which you want to create a
configuration checkpoint and name the checkpoint. For details about creating a checkpoint and rolling
back a configuration, see
your ACE, see the Downgrading Your ACE Software section in the Release Note for the Cisco 4700
Series Application Control Engine Appliance.
