Step 11 Begin the on-line software upgrade by entering the following command:
upgrade online image_url config cfg_url [-noconfirm]
The SMCs within the system load the new operating system image and the local file system is synchronized. The system
then updates all standby packet processing cards. Next, it begins to update each active packet processing card, one at a
time. The system monitors all sessions being processed by active packet processing cards. When all sessions facilitated
by a specific Session Manager task are either self-terminated or automatically terminated based on the thresholds
configured in step 8, the system migrates the packet processing cards in active mode to standby mode. Each new
standby packet processing card is upgraded and rebooted. Once booted, the card is placed back into service as an active
packet processing card.

Step 12 Optional: To view the status of an on-line software process, enter the following command from the Exec mode prompt:
show upgrade
This command displays the status of the on-going on-line software upgrade. Once all SMCs have been upgraded, the
full configuration file is loaded, the NPUs are taken out of global bypass mode, and the system is returned to normal
operation. When the on-line software upgrade has been completed, all sessions on the system will be new and all system
statistics will have been reset.Upon completion of the software upgrade, the system will automatically begin accepting
new sessions, using the pre-existing configuration that was running. All system statistical counters will have been reset
to zero.

Aborting an On-line Software Upgrade
Abort the on-line software upgrade process by entering the following command:
abort upgrade [-noconfirm]
Important:
The abort upgrade command can only be used during Stage 1 (busy-out) of an on-line software
upgrade.
Restoring the Previous (Pre-online Upgrade) Software Image
If for some reason you need to restore the system to the software image that was running before the online upgrade
process, perform the On-Line Software Upgrade again and specify the locations of the original software image and
configuration files.

configuration files.
Off-line Software Upgrade
An off-line software upgrade can be performed for any system, upgrading from any version of operating system
software to any version, regardless of version number. This process is considered off-line because while many of the
steps can be performed while the system is currently supporting sessions, the last step of this process requires a reboot to
actually apply the software upgrade.

This procedure assumes that you have a CLI session established and are placing the new operating system image file
onto the local file system. To begin, make sure you are at the Exec mode prompt:
