Software Upgrade
You can perform the following types of software upgrades on the HA system:
Software Upgrade with Device Reset: Both active and redundant devices burn and
reboot with the new software version. This method is quick and simple, but it disrupts
traffic (i.e., traffic affecting).
Hitless Software Upgrade: This method maintains service (i.e., not traffic affecting).
For more information, see ''Software Upgrade Wizard'' on page 587.
