An administrator is upgrading their external Platform Services Controllers and vCenter Server Appliance, and also migrating vSphere Update Manager version 6.0 to version 6.5. Which is the correct orde

The correct sequence is to upgrade the external Platform Services Controller first because vCenter Server depends on it for SSO and authentication services. After the PSC is upgraded to 6.5, the vCenter Server Appliance is upgraded next, and finally vSphere Update Manager is migrated from 6.0 to 6.5. This order ensures each component is compatible with its dependencies before the next component is touched.

This option presents an incorrect step ordering after the initial PSC upgrade, violating the required dependency sequence between vCSA and VUM.

This option places VUM migration out of order relative to the vCSA upgrade, which would cause compatibility issues since VUM is embedded in vCSA 6.5.

Upgrading the vCenter Server Appliance before the external PSC violates the required dependency order and will cause authentication failures during the upgrade process.
