@asmar I don’t think Epicor cares about the VMWare version or even knows. They have the generic thick provisioning, vmxnet3 and paravirtual info you will find in a lot of places.
You need to check the VMWare ESXi compatibility to your hardware to get to the latest you can and use PDT or dskspd to check your system.
I am running on the same blades and drives I did for E9 and have just updated the ESXi. It was overkill to make E9 better and now that E10/11 is faster it is still good.
