8 Migrating or Upgrading Converged Application Server

This chapter provides instructions for upgrading your Oracle Communications Converged Application Server system.

About Migrating or Upgrading Converged Application Server

Because of architectural changes in the underlying WebLogic Server platform, there is no automated upgrade path. Instead, you must manually upgrade or migrate your Converged Application Server to the latest version.

High Availability

During your upgrade and migration, you can introduce high availability (HA).

For information about HA environments, see "Failure Prevention and Automatic Recovery Features" in the Converged Application Server Administrator's Guide.

Migrating or Upgrading Converged Application Server

To manually upgrade or migrate your Converged Application Server system:

  1. Back up all of your old Converged Application Server domains.
  2. Install Converged Application Server 8.0 on any servers hosting the Administration Server or Managed Servers (engines). See Installing Converged Application Server and the Cloud Deployment Guide.
  3. Create your new Converged Application Server domains. See Creating and Configuring Converged Application Server Domains for more information.
  4. Copy the WAR or EAR files from your old domains into your new domains.
  5. Verify the domain administration settings on your new Converged Application Server system. See Verifying Your Domain Administration Settings.
  6. Install and deploy your old applications to your new system.
  7. Verify that the applications deployed on your new Converged Application Server system work as expected.

Verifying Your Domain Administration Settings

In this section, the system you are upgrading from is called old (for example, your old system), and the system you are upgrading to is called new (for example, your new system).

  1. Start your new Converged Application Server Administration Server.
  2. Log in to your new Converged Application Server Administration Console:
    http://<address>:<port>/console
  3. Verify that your new domain configuration is correct. In particular, pay attention to the following settings:
    • SSL is enabled/disabled consistently on every node machine
    • All security authentication providers are listed and configured correctly
    • Coherence security has been configured
    • Work managers are configured correctly
    • The application router is configured correctly
    • The call state storage and data tier has been configured

    For information about configuring the Administration Console, see Converged Application Server Administrator Guide.
