You can delete a cluster from a workload domain. Datastores on the ESXi hosts in the deleted cluster are destroyed
You cannot delete the last cluster in a workload domain. Instead, delete the workload domain. See Delete a VI Workload Domain.
Prerequisites
- If you are deleting an NSX-T workload cluster, delete any workload VMs created outside VMware Cloud Foundation before deleting the cluster.
Migrate or backup the VMs and data on the data store associated with the cluster to another location.
