FileNet P8 Application Engine, Content Platform Engine, Version 5.2              

Upgrading and configuring Application Engine

You can upgrade Application Engine from version 3.5 or version 4.0 to version 4.0.2. The procedures for upgrading Application Engine vary depending on the version that you are upgrading.

Important: Before you start to upgrade the Application Engine software, ensure that you are at the correct version and fix pack level, as indicated in Plan and Prepare Your Environment for IBM® FileNet P8.
  1. Preparing for Application Engine upgrade
    Before you upgrade your Application Engine installation, you must prepare your existing configuration for the upgrade. This preparation includes backing up existing files and undeploying your web application.
  2. Upgrading Application Engine
    After you have prepared your existing configuration, you can begin the Application Engine upgrade. The tasks for upgrading Application Engine differ depending on whether you start from version 3.5 or version 4.0.
  3. Installing Application Engine software updates
    If any required fix packs and interim fixes exist for Application Engine, you must install these software updates.
  4. Installing the latest Content Engine client files on Application Engine servers
    The Content Engine Client software enables communication between the Application Engine and the Content Engine. Install the latest release or fix pack version of the Content Engine Client files on all Application Engine servers.
  5. Manually copying custom data
    If your custom data was not retained in the upgrade, you must manually copy the data from the version 3.5 or 4.0.1 backup files (deploy_backup) to the upgraded directories.
  6. Deploying upgraded instances of Application Engine
    After you upgrade and configure Application Engine, deploy your client application, Workplace, on your application server. It might be necessary to re-create the WAR or WAR and EAR files before you deploy.
  7. Completing post-upgrade Application Engine configuration
    After you upgrade and deploy your Application Engine instances, you can complete additional configuration. Actions include modifying a configuration file, verifying Workplace sign-in, and establishing the Process Engine connection point.
