Software Upgrade
You can perform the following types of software upgrades on the HA system:
■ | Software Upgrade with Device Restart: Both active and redundant devices save and restart 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). |
