Scheduling a Cluster Upgrade

Starting from ArubaOS 8.4.0.0, scheduled cluster upgrade allows you to schedule the upgrade to a specified time to avoid manual intervention. The cluster is upgraded automatically at the scheduled time. You can view, delete, or reschedule the scheduled cluster upgrade.

You can also schedule cluster upgrade for one or more profiles at the same time or different times.

When a Mobility Master reboots or a process restarts, this feature has the ability to preserve the configured scheduled upgrades. It also allows you to synchronize the scheduled upgrades to a standby Mobility Master. If a Mobility Master has active and standby devices configured, then the scheduled upgrade information will be synchronized between active and standby through database synchronization. The upgrade is initiated when the Mobility Master becomes active.
