vCenter Server Appliance 6 HOSTNAME CHANGE

Hi everyone,

I'm running into a problem with my VCSA.

We migrated, sucessfully, our VCSA 5.5 to VCSA 6 a little while ago.

We are now in need of changing the FQDN of the VCSA.

So I logged in with the "administrator@vsphere.local" in the Web client and went in Administration -> Deploiement -> System configuration -> Nodes

I went into Networking and got the " com.vmware.appliance.version1.networking.dns.hostname.set: Hostname is used as network identity, set operation is not allowed.

Details: {} "

We are configured with a static IP and our DNS server is correctly setup.

We rebooted the server quite a few times with still the same error.

Thanks for your help.
