vSAN version 6.6, the 6th generation of the product was recently released and is the biggest update yet. This release includes 20+ new features and various performance enhancements. Please keep in mind that VMware does not support upgrading from vSphere 6.0 U3 to vSphere 6.5 as per vSphere upgrade policy. Please see VMware KB https://kb.vmware.com/kb/2149840.
All this means that VMware does not support “back in time” upgrades (vSphere 6.5.0 was released 5 months before vSphere 6.0 U3). Please review vSphere upgrade matrix http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php#upgrade.
