I was told before that with vSphere 4 a vmotion between these families should not be a problem, but I am getting an error that the CPU host bits are not compatible... VM KB 1993 (http://communities.vmware.com/thread/161608;jsessionid=0015A69B417697CE8217E527E2B93EF8).

Just wondering if this is a supported config from Dell/VM and if I follow the steps listed in the KB, will I get this working and will it really be supported.

Anyone else doing similar with different models?
