Upgrading a Single Standalone Server to an HA Configuration

To change a single standalone server to the active server in an HA configuration, you must configure a Shared IP address on the existing standalone server, and then configure a standby server with the same shared IP address.

The new Shared IP address is used to log in to the system, and is used for network communication by the controllers. 

Note     The active and standby servers must have unique Eth0 IP addresses.

See the Upgrading the Server Software for more information.

If possible, we recommend assigning two IP addresses to a single standalone ICPAM server: Eth0 and the Shared IP Address. This enables you to switch from a standalone configuration to an HA configuration without changing the IP address required for user logins.
