Most VMware migration plans inventory VMs, clusters, storage, and licensing. Very few inventory the operational assumptions attached to vCenter itself. The result is predictable: the hypervisor migration succeeds in staging, but production operations degrade because the virtualization control plane functions the organization depended on were never modeled as architecture.

This isn't a technology maturity problem. Nutanix AHV, Proxmox, KVM-based platforms, and Azure VMware Solution all run workloads competently. The failure pattern is architectural: teams migrate the execution layer and discover — weeks or months later — that the governance layer migrated nowhere.

The name for this condition is Control Plane Dependency Drift : the accumulation of operational processes, integrations, and governance assumptions that become tightly coupled to a specific infrastructure control plane over time, making platform replacement far more complex than workload migration alone.…
