An administrator needs to scale out the VMware Cloud Foundation (VCF) Automation node from a...

VCF 9.0 states for the Simple Automation model: “Single node… Applies to Small… Can be scaled out to the high availability model by resizing the node to Medium or Large, which also forces the scale out to 3 nodes.” In addition, the Day-N procedure confirms the action is a Scale (scale-out) operation: “Scale VCF Automation… choose a larger target deployment type such as Medium or Large…” and provide “Additional VIPs” and a “Cluster Node IP Pool” (Medium requires a minimum of four IPs), then submit the scale out request. Therefore, moving from Small (Simple) to Medium necessarily transitions to the High Availability (3-node) model rather than remaining a single medium node. This aligns the form factor with the documented model behavior and the fleet management workflow.
