The change will go into effect immediately and you will now be able to vMotion a VM configured with vGPU. To enable vGPU vMotion, you just need to update the following vCenter Server Advanced Setting to true using the vSphere UI.

Since this question has come up a few times this week, I thought it is worth a quick blog post on how to enable the new vGPU vMotion feature which is now available in latest vSphere 6.7 Update 1 release.
