But guys be careful! According to the VMware compatibility matrix, it is not possible yet to upgrade from vSphere 6.5 U3 to 6.7. So if you plan to do so, avoid this update.


As you can see VMware continues to improve and provide fixes to vSphere 6.5. This is a good thing as I’m sure that some customers might still be stuck or are planning to migrate to that version. Well this update might be the last for vSphere 6.5 as VMware is mainly focusing on vSphere 6.7 and the upcoming 7.x that should be announced soon.
