Can I vMotion a VM while IO Insight is tracing it?

Today during the Polish VMUG we had a great question, basically, the question was if you can vMotion a VM while vSAN IO Insight is tracing it.

VMs which are not stretched in a stretched cluster, which policy to use?

I’ve seen this question popping up regularly. Which policy setting (“site disaster tolerance” and “failures to tolerate”) should I use when I do not want to stretch my VMs?
