Esxi5.0 to 5.1 Live Vmotion

Hi Guys,

I have two Esxi host, one running 5.1 the other running 5.0 both R710 but the CPU models are different.

and Unfortunately the one that is running 5.0 the CPU does not support AES-NI feature set and due to this I can't do vMotion to shift my vms to another host.

I thought vmware can support different hardware in terms of vmotion or have I seen wrong on youtube?

or is there any other way around of this problem?

Regards,

PS:

This is what Dell Techy wrote to me:

"I have do some research and found that the processor which is in your server (E5530) is not support  for the AES function.

Only 56xx series of processor is supported for  the AES function."
