Chapter A Upgrading Your ACE Software Before You Begin Changing the www User Password Before you upgrade to software version A1(8.0a) or higher, 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. See Chapter 2, Configuring Virtualization, in the Cisco 4700 Series Application Control Engine Appliance Virtualization Configuration Guide for details on changing a user account password. In this case, the user 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-configuration file. 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 Chapter 5, Managing the ACE Software.

Chapter A
Upgrading Your ACE Software
Before You Begin
Changing the www User Password
Before you upgrade to software version A1(8.0a) or higher, 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.
See Chapter 2, Configuring Virtualization, in the
Cisco 4700 Series Application
Control Engine Appliance Virtualization Configuration Guide
for details on
changing a user account password. In this case, the user 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-configuration
file.
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
Chapter 5, Managing
the ACE Software
