ACOS supports two methods for upgrading.
Upgrading via the upgrade center
The upgrade center in AOC enables you to perform both cluster and kernel upgrades in one place, significantly reducing operational complexity and improving both upgrade efficiency and success rate. If your cluster version supports upgrades via the upgrade center, it is recommended to follow the Arcfra Upgrade Center operation and maintenance for the upgrade process.
Upgrading via the command line
By executing the command line upgrade operation on a single node of the cluster, the entire cluster can be upgraded without manual intervention, and detailed upgrade logs can also be viewed.
