While most versions of VMFS are backwards-compatible, it is a best practice to verify and use the latest version of VMFS recommended by VMware. Typically, new VMFS versions are bundled with an ESXi upgrade. As a migration path, VMware vCenter allows administrators to use VMware vSphere Storage vMotion to migrate virtual machines to new VMFS datastores formatted with the latest version.
Note: PowerStore X model appliances use VMware vSphere Virtual Volumes (vVols) storage containers for storage of virtual machines that run on internal PowerStore X model nodes. While it is not a best practice, block volumes can only be presented to the internal ESXi hosts in the PowerStore X model using the REST API.
