At the Choose DR Site step, specify the FQDN name or IP address of the target VAO server in the DR site.
When you install VAO in the DR site, you can customize the default server communication port number (8888). However, the Initial Configuration Wizard does not provide you an option to change the port number used to connect to the DR site. In this case, at the Choose DR Site step, you must enter the name of the target DR VAO server in the following format: <dr_server_name>:<port>. Otherwise, the Production site will not be able to connect to the DR site.
