In one of my labs all the hosts and VMs are on the VMware distributed switch to mimic one of the production environment. When I planned for the upgrade from vSphere 5.5 to 6.5 in that lab and started deploying the VCSA 6.5 using the .iso image - I came across this. So, VMware doesn't support distributed switches with non-ephemeral port group when deploying the VCSA and PSC on 6.5. I read few articles and most of them suggested to migrate your vCenter 5.5 to Standard switch as well as build the new VCSA 6.5 on standard switch for smooth migration. But what if environment is 100% on distributed switch and going back and creating standard switch is not an option. Well, there is a work around to get past this screen. You will need to create a port group on distributed switch with "ephemeral binding". Once you create that port group on the distributed switch, all the VLANs/port groups from that distributed switch would show up and you can deploy ...
