VCSA 5.5 to 6.0 upgrade is changing FQDN

I'm getting this message during the upgrade process to 6.0 on our VCSA that I haven't seen in any of the guides I've read online:

Will this have any affect on any fqdn-based connections we have to the appliance (e.g. our Citrix XenApp environment, Veeam) if we don't change the certificate and keep our static DNS entry for the VCSA the same?
