Upgrading a vSphere + vSAN environment to a full VMware Cloud Foundation deployment requires introducing the components that make up the integrated software-defined data center (SDDC):
A. NSX – Provides network virtualization, overlay segments, distributed firewalling, and routing required in VCF.
B. SDDC Manager – The core management and lifecycle automation tool of VCF, responsible for bring-up, patching, and upgrades.
E. vSphere Supervisor – Required to enable VMware Tanzu Kubernetes Grid (TKG) and modern application deployment in VCF environments.
Why not the others?
C. VCF Identity Broker – Provides federated authentication but is not mandatory for initial upgrade. It is optional depending on identity requirements.
D. VCF Operations – This is VMware Aria Operations (for monitoring/analytics). While strongly recommended, it is not required to upgrade from vSphere/vSAN to VCF.
