Step 1 If you configured Network Time Protocol on the publisher server, ensure that it is synchronized with an NTP server before you install the subscriber server. From the Command Line Interface on the publisher server, enter utils ntp status. Ensure that the output indicates that the server is synchronized with an NTP server.
Note If the publisher server is not synchronized with an NTP server, installation of the subscriber server will fail.
Note When you are installing Cisco Unity Connection on a virtual machine, you must specify an external NTP server.
Step 2 On the First Node Configuration window, read the Warning and make sure you have correctly configured the publisher server. To continue with the installation of the subscriber server, click OK.
The Network Connectivity Test Configuration window displays.
Step 3 During installation of a subscriber server, the system checks to ensure that the subscriber server can connect to the publisher server.
•To pause the installation after the system successfully verifies network connectivity, choose Yes.
•To continue the installation with a pause, choose No.
The First Node Access Configuration window displays.
Step 4 Enter the connectivity information for the publisher server and choose OK.
The system checks for network connectivity.
If you chose to pause the system after the system successfully verifies network connectivity, the Successful Connection to First Node window displays. Choose Continue.
Note If the network connectivity test fails, the system always stops and allows you to go back and reenter the parameter information.
The SMTP Host Configuration window displays.
Step 5 If you want to configure an SMTP server, choose Yes and enter the SMTP server name.
Note To use certain operating system features, you must configure an SMTP server; however, you can also configure an SMTP server later by using the operating system GUI or the command line interface.
The Platform Configuration Confirmation window displays.
Step 6 To start installing the software, choose OK, or, if you want to change the configuration, choose Back.
Step 7 When the installation process completes, you get prompted to log in by using the Administrator account and password.
Re: How to add Unity connection Subscriber to Unity connection P

I have a Unity Connection Publisher and Subscriber in a cluster. We are planning to move our Data Center to new location. I will install new Unity Connection Subscriber, can this new server join the cluster without deactivation/decommissioning the existing subscriber?
This will not work as Unity Connection supports only a two server cluster unlike CUCM;
Cisco Unity Connection Cluster Overview
Unity Connection supports a Unity Connection cluster configuration of two Unity Connection servers to provide high availability and redundancy. The Unity Connection servers handle calls, HTTP, and IMAP requests. If only one server in the Unity Connection cluster is functioning, the remaining server preserves the system functionality by handling all calls, HTTP requests, and IMAP requests for the Unity Connection cluster. Note that each server in the Unity Connection cluster must have enough voice messaging ports to handle all calls for the Unity Connection cluster.
The first server installed is the publisher server for the Unity Connection cluster; the second server installed is the subscriber server. These terms are used to define the database relationship during installation. The separation of roles is consistent with the Cisco Unified Communications Manager cluster schema in which there is always one publisher server and multiple subscriber servers. (Note that Unity Connection runs on the Cisco Unified CM platform). Unlike a Cisco Unified CM cluster, however, Unity Connection supports only two Unity Connection servers in the Unity Connection cluster.
