Increasing SSH keys from 1024-bit to 2048-bit keys

Is this procedure https://support.f5.com/csp/article/K26031800 also valid for 14.X.X ? Or maybe there is another one ?

It was enough to regenerate the SSH keys, so one command:

"/usr/bin/keyswap.sh -genkeys" did the trick.

    Just this command will help change SSH keys from 1024 to 2048 bit.

    "/usr/bin/keyswap.sh -genkeys" 

    Or this is addition to K26031800.

      In my case (v14.x) it was enough to issue this one command, altough v14.x should have 2k by default, as Dario commented ...
