WebSphere brand IBM WebSphere Presence Server, Version 7.0

Migrating from a previous release of IBM WebSphere Presence Server Component

For users of previous versions of the Presence Server product, the topics in this section describe the process of migrating your existing configuration to the current version.

Before you begin

Deploy WebSphere® Application Server Network Deployment version 7.0.0.1 or 6.1.0.21.

ANT must be installed on the server where you configure IBM® WebSphere Presence Server Component. You can obtain ANT from the Apache Ant Web site: http://ant.apache.org.

About this task

When migrating from a previous version of Presence Server, perform the following steps:

  1. Create new database instances using the instructions in the topic Preparing the databases.
  2. Copy your version 6.2 configuration data to a temporary file, using one of the scripts (db2Get or oracleGet) that are provided on the installation medium:
    • DB2 ant db2Get -f GetPresenceConfiguration.xml -DdbUserName=db_user -DdbUserPassword=db_user_pw -DdbServer=hostname -DdbName=db_name -DdbPort=port -DjdbcDir=drivers_path -DconfigurationFileName=dest_file_name
    • Oracle ant oracleGet -f GetPresenceConfiguration.xml -DdbUserName=db_user -DdbUserPassword=db_user_pw -DdbServer=hostname -DdbName=db_name -DdbPort=port -DjdbcDir=drivers_path -DconfigurationFileName=dest_file_name
    where:
    • db_user is the name of the database user.
    • db_user_pw is the password for the database user.
    • hostname is the fully qualified name of the database host.
    • db_name is the name of the database.
    • port is the port number through which the database is accessed.
    • drivers_path is the path to the JDBC drivers for the database.
    • dest_file_name is the directory path and name for the temporary file in which your configuration data will be stored.
  3. Create a new cluster for Presence Server on the WebSphere instance. Refer to the topic Creating the cluster for details.
  4. Install the Presence Server version 7.0 program code using the procedures in the topic Installing the Presence Server product.
  5. Copy the configuration parameters you saved in step 2 to the version 7.0 SystemConfiguration.xml file
  6. Route all new SIP/HTTP requests to the new Presence Server version 7.0 proxy server. Old sessions will continue to be routed to the version 6.2 cluster. When long-running version 6.2 sessions end, they will be rerouted to the new version 7.0 cluster.
  7. Monitor performance on the version 6.2 cluster. When the Presence Server indicators reach zero, or when you believe that a suitable threshold of activity has been reached, stop the Presence Server application on the version 6.2 cluster. The WebSphere Performance Monitoring Infrastructure (PMI) is recommended for monitoring performance. For details, refer to the topic Monitoring system performance using WebSphere PMI.
  8. Uninstall the Presence Server version 6.2 program code using the procedures in the topic Uninstalling IBM WebSphere Presence Server Component.
