How to change vCenter Appliance (VCSA) 6.x IP Address?

By | July 28, 2016

Recently, I have had to change IP addresse of some vCenter Appliances (VCSA) 6.0 U2 in our environment. Changing IP address is possible (however officially not supported) and it's straightforward if you deployed VCSA correctly - using FQDN. If you deploy VCSA using IP address as FQDN, you can not change IP address.

To change IP address of VCSA 6.x you need to follow the below steps:

  1. Log in to VCSA using SSH (if you do not know/remember the root password please follow this guide to reset it) and modify /etc/hosts.How to change vCenter Appliance (VCSA) 6.x IP Address 8change IP address and save by wq!

  3. Log in to VCSA via VAMI (https://VCSA_ip:5480/) using root account and change IP address to a new one.How to change vCenter Appliance (VCSA) 6.x IP Address 1

  5. Wait when vCenter Appliance is restarted and services are running (e.g. Web Client). It needs some minutes to be completed.

It's really important to deploy vCenter Appliance (VCSA) using FQDN, no IP Address.

    You should note for the record this is not officially supported by VMware at this time. There will be Database issues and some of the services will not start.

    Wouldn't there be potential incompatibility issues on other vCenter related services unless you regenerate certificates and ensure those certificates are deployed to all relevant applications as well?
