Due to an issue with a vCenter Server and all of its backups, I had to attach ESXi hosts with vDS to a new vCenter Server. This worked (although it might not be supported) after creating a vDS with the exact same name, and settings on the new vCenter. As I said, it worked, but no gaurantee.
However, folders, and permissions are defined on the vCenter Server, i.e. not on the ESXi hosts themselves, so these need to be reconfigured on the new vCenter Server.
