The netadmin user is the preferred way of configuring networking
The preferred way of administering any of the appliance network configuration is to use the netadmin user account. The netadmin user account enables you to change network, hostname and gateway settings. You can also use the netadmin user to reboot the appliance.
If you change the IP address of the appliance, you will also need to update proxy configurations (known appliance in the proxy manager), and for consolidation you will need to delete and re-create the existing connections.
