Question:

I have USS installed in my existing Service Management 14.1 environment.  I want to run USS on a different server.  How can I move my existing USS installation to the other server?

Environment:
CA Service Management 14.1 with Unified Self Service installed
Answer:

 

Throughout this document, we will refer to the original USS server as "Node 1", and the new server that will host USS as "Node 2"

Follow these steps:

  1. Stop the Unified Self-Service services on node 1.
  2. Create backup of node 1:
    • (Windows) Run TakeBackup.bat from the bin folder of the Unified Self-Service installation directory.
    • (Linux) Run TakeBackup.sh
    Backup is created in Unified Self-Service_installation\CAOpenSpaceBackup.car file of the Unified Self-Service installation directory.
  3. On node 2, install the similar configuration Unified Self-Service as set up in node 1:
    1. Select Use existing database option.
    2. Ensure that you use the same database host name as used during the Unified Self-Service node1 setup.
    3. Select node1 backup CAOpenSpaceBackup.car.  Note: Ensure user has all the privileges according to the basic installation.
    4. Complete the installation

Finally, ensure that Node 2 has the same USS patches installed as Node 1.  You may now start USS on Node 2, but you do not need to start it on Node 1.  Node 2 will now run independently of Node 1.

Additional Information:

This is identical to setting up a clustered USS setup, but you do not start the original node in the cluster: https://docops.ca.com/ca-service-management/14-1/en/implementing/implementing-ca-service-management-14-1/how-to-set-up-the-cluster-environment-for-unified-self-service#HowtoSetuptheClusterEnvironmentforUnifiedSelf-Service-Configure_the_Load_Balancer
