Overview of Upgrading ACE Software Chapter A Upgrading Your ACE Software Overview of Upgrading ACE Software The ACE comes preloaded with the operating system software. To take advantage of new features and bug fixes, you can upgrade your ACE with a new version of software when it becomes available. In the Admin context, you will use the copy command in Exec mode to manually upgrade the ACE software. After the software installation is finished, set the boot variable and configuration register to autoboot the software image. Then, reboot the appliance to load the new image. To minimize any disruption to existing network traffic during a software upgrade or downgrade, deploy your ACE appliances in a redundant configuration. For details about redundancy, see Chapter 7, Configuring Redundant ACE Appliances. Before You Begin 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 • Changing the www User Password • Checking Your Configuration for FT Priority and Preempt • Creating a Checkpoint Changing the Admin Password Before you upgrade to software version A1(8.0a) 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 only be able to log in to the ACE through the console port. See Chapter 1, Setting Up the ACE for details on changing the admin account password. Cisco 4700 Series Application Control Engine Appliance Administration Guide A-2 OL-11157-01
