Replace the foreman proxy ssh keys

CentOS 7.9
Katello 4.4
Foreman 3.2

I have an older Foreman / Katello setup that is currently managing our hosts. I would like to copy off the foreman-proxy ssh key (private and public) and put them on the new Foreman / Katello host. Do I just copy them over and overwrite the keys or is there a foreman-installer command I can use to tell it to use a different set of key?

Just copy them over, if I recall correctly the installer can only generate new keys and just leaves existing keys alone.

Ok so then unless you have created smart proxies or content hosts the keys are not used. (Its not used internally for anything. Except maybe a new smart proxy.)
