Uninstall and Reinstall the Identity Manager Server on a WebSphere 6.0.2.17 Cluster

Important! The following procedure applies in specific situations. Use this procedure to uninstall and reinstall the Identity Manager Server only if you were referred here by Select the Right Upgrade Procedure.

To avoid port conflicts, we recommend uninstalling WebSphere 6.0 before installing the supported version of WebSphere. However, you must first back up the IdentityMinder EAR as described in Step 3 of the following procedure.

To uninstall and reinstall the Identity Manager server on WebSphere 6.0.2.17 cluster

1. Install the minimum supported version of WebSphere and the minimum supported JDK version.

   Note: See the CA Identity Manager support matrix on CA Support for the latest supported versions.

2. Create a cluster with one member.

   See the WebSphere Cluster Setup section in the Installation Guide for details.

3. Perform the prerequisite steps.

   Note: Be sure to back up the IdentityMinderEAR. Also, If the system where CA Identity Manager is to be installed contains SiteMinder and you are using CA Directory for your SiteMinder policy store, we recommend that you do not install the Provisioning Directory on this system.

4. Uninstall the Identity Manager Server. See the Uninstallation and Installation appendix of the Installation Guide.
5. If you did not uninstall WebSphere 6.0, stop the older version of WebSphere.
6. Start the new version of WebSphere.

   Note: If both versions of WebSphere use the same port number, they cannot be running at the same time.

7. Perform a new installation of the Identity Manager Server. Do not use existing messaging store databases with the new installation.

   Note: For more information, see How to Install CA Identity Manager on a WebSphere Cluster in the Installation Guide.

   Be sure to provide the existing CA Identity Manager database credentials during the install.

   Important! If you have different database stores for task persistence, workflow, audit, and reports, update the data sources to point to the separate stores.

8. Upgrade the workflow database.
9. Export the Directories and Environments from the SiteMinder Policy Store.
10. Migrate the Task Persistence data.
11. Restore all customizations to the cluster.
12. Perform post-upgrade configurations.
