The customer should proceed via the Self-Service Upgrade (SSU) portal available on Pure1 Manage.
Pure Storage has transitioned significantly toward a self-service model for routine software upgrades to provide customers with greater flexibility and immediacy.
Pure1 Manage: This cloud-based management platform includes a "Software Lifecycle" or "Upgrade" widget. It automatically checks the array's health, compatibility, and readiness for various Purity versions.
Process: The customer can select the target Purity version directly in the portal. Pure1 then orchestrates the "Pre-Flight Checks" (Remote Audit) to ensure the array is healthy. Once passed, the Purity software is downloaded directly to the array, and the customer (or the engineer) can trigger the upgrade at their convenience without needing to schedule a specific window with a live Support engineer.
Invalid Options: Options A and B describe legacy or unsupported workflows. Customers do not manually download Purity ISOs to USB drives or run raw pureinstall CLI commands manually; these methods lack the automated safety checks and cloud-based verification provided by the SSU ecosystem.
