scp jump through gateways

Dmitry A. thoughtfully pointed out an option to transfer files across domains with scp, assuming there is an intermediate ssh server.  Here is an example from a STAR OLP machine to one of the STAR database servers:
[onl03] ~/> scp -o 'ProxyJump' /etc/services
Note though that the ProxyJump option was added to openssh in version 7.3.
Red Hat EL 6 and its derivatives have openssh-5.x as the stock packages, so will not have this option available.
