Software Upgrade Quick Start Chapter A Upgrading Your ACE Software Table A-1 Software Upgrade Quick Start (continued) Task and Command Example 7. Enter the show ft group detail command in Exec mode to verify the state of each appliance. Upgrade the ACE that has its Admin context in the STANDBY_HOT state (ACE-2) first by entering the reload command in Exec mode. After ACE-2 boots up, it may take a few minutes to reach the STANDBY_HOT state again. Configuration synchronization is still enabled and the connections through ACE-1 are still being replicated to ACE-2. Note Do not add any more commands to the ACE-1 configuration. At this point in the upgrade procedure, any incremental commands that you add to the ACE-1 configuration may not be properly synchronized to the ACE-2 configuration. host1/Admin# reload This command will reboot the system Save configurations for all the contexts. Save? [yes/no]: [yes] 8. Perform a graceful failover of all contexts from ACE-1 to ACE-2 by entering the ft switchover all command in Exec mode on ACE-1. ACE-2 becomes the new active ACE and assumes mastership of all active connections with no interruption to existing connections. host1/Admin# ft switchover all 9. Upgrade ACE-1 by reloading it and verify that ACE-1 enters the STANDBY_HOT state (may take several minutes) by entering the show ft group detail command in Exec mode. Because both ACE-1 and ACE-2 are running the same version of software now, configuration mode is enabled. The configuration is synchronized from ACE 2 (currently active) to ACE-1. If ACE-1 is configured with a higher priority and preempt is configured on the FT group, ACE-1 reasserts mastership after it has received all configuration and state information from ACE-2, making ACE-2 the new standby. ACE-1 becomes the active ACE once again. host1/Admin# reload This command will reboot the system Save configurations for all the contexts. Save? [yes/no]: [yes] 10. Enter the show ft group detail command to verify that ACE-1 is in the ACTIVE state and ACE-2 is in the STANDBY_HOT state.
