the hostname simply reflects the system's identity when you log on but is not used for vpn (ike gw config) or ssh (host certificate based on fqdn op IP)

 

eg. if you access the host by FQDN and have certificates created for those fqdn, and you intend to change the FQDN to reflect the new hostname, then you will need to create a new certificate
