You can change the vCenter Server ID, managed address, and name. Usually, you do not need to change these settings, but you might need to make changes if you run multiple vCenter Server systems in the same environment.

Required privilege: Global.Settings


In the vSphere Web Client, navigate to the vCenter Server instance.


Select the Manage tab.


Under Settings, select General.


In the Edit vCenter Server Settings dialog box, select Runtime Settings.


In vCenter Server unique ID, type a unique ID.

You can change this value to a number from 0 through 63 to uniquely identify each vCenter Server system running in a common environment. By default, an ID value is generated randomly.


In vCenter Server managed address, type the vCenter Server system address.

The address can be IPv4, IPv6, a fully qualified domain name, an IP address, or another address format.


In vCenter Server name, type the name of the vCenter Server system.

If you change the DNS name of the vCenter Server, use this option to modify the vCenter Server name to match.


Click OK to save your changes and close the dialog box.

If you made changes to the vCenter Server system unique ID, you must restart the vCenter Server system for these changes to take effect.
