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 ?

# tmsh show sys software | grep yes
HD1.2    BIG-IP   14.0.0  0.0.2187     yes  complete
 
# openssl rsa -noout -text -in /var/ssh/ssh_host_rsa_key | grep -i key
Private-Key: (2048 bit)

KR,

Dario.
