My go-to tool when things aren't looking quite right is the Interoperability Matrix Tool. Anyway, when I select VSC 6.2, vCenter 6.5 is disabled:
If I select 6.21, vCenter 6.5 gets re-enabled, so it looks like that'd be your safer path insofar as supportability... If you did get things working in your present state with 6.2 and then ran into other issues, you might still end up wedged with NetApp in that your configuration wouldn't be certified as supportable.
Hope that helps,
