Updating Feature Server

Warning

This Administration Guide applies ONLY to the Legacy SIP Feature Server 8.1.200.xx release. Unless you have been told to use this documentation, use the current 8.1.2 Administration Guide

Use this procedure to update to a minor version of SIP Feature Server 8.1.2. Note the following restrictions:

• Upgrading from SIP Voicemail to SIP Feature Server requires a fresh installation.
• You cannot change installation modes (cluster to standalone or vice-versa).
• If you are upgrading from a restricted release of SIP Feature Server 8.1.2 (any version prior to 8.1.200.85), you must manually restore the vms_host parameter, as follows:
  1. Open launcher.xml.
  2. In the vms_host section, in the line <format type="string" default="localhost" />, replace "localhost" with "0.0.0.0" or a specific IP address to restrict Feature Server web application access to that address.

To update a single Feature Server:

1. Stop Feature Server.
2. On the Feature Server master node (which is also the Cassandra seeds node), back up all files in the etc folder, which includes the cassandra.yaml file.
3. Back up the database files for all nodes in the Cassandra cluster (because the upgrade propagates changes to all nodes in the cluster). Note the file locations.
4. Install Feature Server from the installation package. During the upgrade, the installer uses the values provided during a fresh installation.
   Note: You can change the destination directory during the installation.
5. Start Feature Server.
