What is the order of operations for software upgrades of Cisco SD-WAN nodes?

Upgrading vBond before vManage is incorrect as vManage is the central management platform that orchestrates upgrades across the entire fabric.

The correct sequence for software upgrades in a Cisco SD-WAN fabric is vManage, then vBond, then vSmart, and finally WAN Edge devices. This order ensures that the central management system is upgraded first, followed by the orchestrator, then the controllers, and lastly the data plane devices, maintaining control plane integrity throughout the process.

Upgrading WAN Edge devices before vSmart controllers is incorrect because vSmart controllers provide central policy and routing to the WAN Edges, and compatibility must be maintained.

Upgrading vSmart before vBond is incorrect; vBond should be compatible with the vManage version before vSmart in the recommended upgrade path.
