Migrating an existing single system image (SSI)

In an SSI system, comprising one or more servers and a number of clients, it is possible to reduce downtime by first migrating the servers and a limited number of clients. A reduced capacity system can then be run with the new Blueworx Voice Response Version 6.1 software, while you migrate the remaining clients.

Procedure

Before you start, make a backup of all the machines in the SSI cluster.

Upgrade one or more clients:
On the first client machine:
  1. Quiesce telephony.
  2. Shutdown Blueworx Voice Response.

    The client is now isolated and can be migrated while the rest of the SSI continues to operate.

  3. On the isolated client, run the command ssirmclient to remove the SSI client.
  4. Upgrade to Blueworx Voice Response as described in Software installation.
Upgrade the server:

In order to upgrade the server, you must first stop all clients. This means that the SSI will not be operational while the server is upgraded.

  1. On the other SSI clients:
    1. Quiesce telephony.
    2. Shutdown Blueworx Voice Response.
  2. On the SSI server:
    1. Run the command ssirmsrv to remove the SSI server.
    2. Upgrade Blueworx Voice Response as described in Software installation.
    3. If the SSI server has telephony, then start telephony.
Restart the reduced system:
  1. Start Blueworx Voice Response on the migrated clients.
  2. Start Telephony.
Migrate and restart the remaining clients:
  1. Upgrade to Blueworx Voice Response Version 6.1.
  2. Start Blueworx Voice Response.
  3. Start telephony.
