I am deploying a new vCenter Appliance and adding hosts from an old environment.
Appreciate your help in this!
Changing Hostname/IP is only supported with 6.7u3 and later. You should take a snapshot from the VCSA before you change it. Why you have add the Hosts first and why not use the right Name and IP from beginning?
Now the change will create a new Cert and this can be challenging for all things that are already connected to the VCSA. But when have to change both (Hostname/IP) it will be also create some trouble.
I have an old vCenter running with same name and IP, I am trying to deploy a new vCenter and moving old hosts to it, and then powering the old one off and changing FQDN and IP for new one. Thought of this just in case I needed to rollback to the old vCenter for any reason.
Would you recommend changing FQDN and IP of old vCenter and deploying the new one with final FQDN and IP?
