Disable TLS Versions on Platform Services Controller
Systems
If your environment includes one or more Platform Services Controller systems, you can use the TLS
Configuration utility to change which versions of TLS are supported.
If your environment uses only an embedded Platform Services Controller, you do not have to perform this
task.
Note Proceed with this task only after you confirm that each vCenter Server system is running a
compatible version of TLS. If instances of vCenter Server 6.0.x or 5.5.x are connected to the
vCenter Server, those instances stop communicating with the Platform Services Controller if you disable
TLS versions.
You can disable TLS 1.0 and TLS 1.1 and leave TLS 1.2 enabled, or you can disable only TLS 1.0 and
leave TLS 1.1 and TLS 1.2 enabled.
Prerequisites
Ensure that the hosts and services that the Platform Services Controller connects to can communicate
using a supported protocol. Because authentication and certificate management is handled by the
Platform Services Controller, consider carefully which services might be affected. For services that
communicate only using unsupported protocols, connectivity becomes unavailable.
Procedure
1 Log in to the Platform Services Controller as a user who can run scripts and go to the directory where
the script is located.
