One of the parts of the upgrade process from vSphere 6.0 to vSphere 6.5 is to upgrade vSphere Distributed Switch.
First and most important prerequisites is to perform a backup of vSphere Distributed Switch. I described the procedure in this blog post How to backup and restore vSphere Distributed Switch. The second prerequisite is to create an ephemeral port for vCenter Server. I described it in the following blog Why vCenter Server needs an ephemeral PortGroup? post why it is important to have ephemeral portgroup for vCenter Server.
