Dear Friend,
Make on you note that vMotion only depend on CPU and network, as you already mention CPU are same and both host connected in vcenter, then it is very easy task to do vmotion, by the way for a power on vm you have to configure a share storage in both host, or you can go for power off vmotion.
Direct answer of your question is - power off you vm and go for migration or Move inventory of that vm from source storage to destination storage.
