ProxyJump was added in OpenSSH 7.3 so systems from a few years ago might not support it. It does the same thing as ProxyCommand with -W %h:%p but you can’t set custom options for the jump connection with ProxyJump.

OpenSSH 7.3 was released on 2016-08-01, so more than 3 years ago. Nobody should be running SSH versions this old (hopefully).

  CentOS 6 lives on in enterprise, unfortunately. (don't know exact OpenSSH version but didn't support -J when I checked earlier)
