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:
- Create new database instances using the instructions in
the topic Preparing the databases.
- 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:
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
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.
- Create a new cluster for Presence Server on
the WebSphere instance. Refer to the topic Creating
the cluster for details.
- Install the Presence Server version 7.0 program
code using the procedures in the topic Installing the Presence
Server product.
- Copy the configuration parameters you saved in step 2 to the version 7.0 SystemConfiguration.xml file
- 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.
- 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.
- Uninstall the Presence Server version
6.2 program code using the procedures in the topic Uninstalling
IBM WebSphere Presence Server Component.
