vMotion between subnets

Our Vmware environment considt of a Windows based vCenter 6 update 3 server and 110 ESXi 6 update 2 hosts. We are in the process of redesigning out network and want to  finally break out our vmotion network into its own vlan. The blades nic layout would look like below. I have read the having vmotion across vlans / subnets is not supported due to the risk of latency. Yet I have see other KB article stating you can do it yet it is not recommended Thoughts?

vmnic0 - mgmt
vmnic1 - mgmt
vmnic2 - vmotion
vmnic3 - vmotion
vmnic4 - guest traffic
vmnic5  -guest traffic

It was old advice in the old days about not supported because of high latency, but networks are usually much better today!

Providing you have good network communications, and you can vmkping between vMotion VMKernel IP Addresses, you are good to vMotion!

We even have long distance vMotion now!
