Preparing for Content Platform Engine upgrade

You must complete several pre-upgrade procedures to prepare Content Platform Engine for upgrade.

Stopping the IBM Content Search Services index dispatcher
You must stop the IBM® Content Search Services index dispatcher before upgrading Content Platform Engine. You will restart the dispatcher after completing the upgrade of IBM Content Search Services.
Stopping and backing up Content Platform Engine before upgrading
Stop all Content Platform Engine-related services and applications and do a backup before doing the upgrade.
Removing the deployed FileNetEngine application
If you are upgrading an existing application server instance, you must remove the existing FileNetEngine application from the web application server to undeploy or uninstall the application EAR file. Removing the existing version ensures a clean deployment of the upgraded version of the Content Platform Engine EAR file.
Copying the configuration profile directory
If you are upgrading to a different application server but using an existing profile, make a copy of the current configuration profile directory.
Updating JDBC drivers and application server JDKs
Your JDBC drivers must be at the supported version.
Clearing the web application server cache
You must clear the cache for the web application server to remove the currently deployed Content Platform Engine data to prevent conflicts with the upgraded version.
