You can disable earlier versions of TLS for port 9087 by modifying the jetty-vum-ssl.xml configuration file. The process is different for Port 8084.

Note: Before you disable a TLS version, make sure that none of the services that communicate with vSphere Update Manager use that version.

Prerequisites

Stop the vSphere Update Manager service. See the Installing and Administering VMware vSphere Update Manager documentation.

Procedure

  1. Stop the vSphere Update Manager service.
  2. Navigate to the Update Manager installation directory, which is different for vSphere 6.0 and vSphere 6.5 and later.
