Can I vMotion VM from a Host ( CPU Haswell ) to EVC cluster ( CPU Skylale with EVC L6 )

I have a 6 chasiss with ~ 100 Blade running VM with CPU Haswell not configured EVC.

We going to buy more Blade with new CPU Skylake.

We dont want every VM online.

I going to create new EVC Cluster ( with EVC L6 ) and than vMotion VM from old Host to new Cluster. Is it possible?

Hi, Yes, this is possible to vmotion between clusters provided networking and storage config is the same.  However if you want to take advantage of the cpu instruction, you have to shutdown the VM and start it again.  Reboot is not enough.

In your situation where you are adding these host as a new cluster then yes you can vMotion from older CPU to newer CPU.

however if you were adding them to an already existing cluster you would need to set the CPU level to Haswell to enable the ability to vMotion in both directions.
