VMware Cloud Foundation 5.2 introduces a new CLI tool, the VCF Import Tool, to convert or import an existing vSphere environment that is not currently managed by VCF into VMware Cloud Foundation.
If you do not already have SDDC Manager deployed, you can deploy it on an existing vSphere environment and use the VCF Import Tool to convert that environment to the VMware Cloud Foundation management domain.
If SDDC Manager is already deployed, you can use the VCF Import Tool to import existing vSphere environments as VI workload domains.
In addition to importing and converting vSphere environments, you can using the
VCF Import Tool to deploy VLAN-backed NSX and sync the SDDC Manager inventory.
