What will happen if I upgrade my ESXi to 6.5 and add upgraded ESXi to new vCenter Server?

Virtual SAN 6.5

I will be able to see my existing vSAN Datastore, but I will not be able to use it.

As of now, i have created a cluster for virtual SAN. My hosts are just a part of my US Datacenter.

When i tried cloning my slax virtual mahine to this vSAN datastore, it gives me error

A general system error occurred: PBM error occurred during PreCloneCheckCallback: pbm.fault.PBMFault;

No VASA Provider for schema namespace (VSAN) found.
