Explanation

Running an Upgrade Precheck from LCM (Life Cycle Manager) is specifically designed to validate that the cluster environment meets all prerequisites before an upgrade begins. Prechecks identify potential blockers such as insufficient disk space, incompatible software versions, degraded cluster health, failed services, or unsupported configurations-allowing the administrator to resolve issues before the maintenance window rather than discovering them mid-upgrade. This is the most proactive and efficient way to reduce upgrade risk. Upgrading AOS immediately (A) skips the validation step. Rebooting CVMs (C) or hosts (D) one-at-a-time before the upgrade is unnecessary and potentially disruptive; rolling reboots occur as part of the managed upgrade process itself.
