Uninstalling a Portal Application Archive (PAA) file update

If there are issues with the Portal Application Archive (PAA) file update, we can uninstall the update and return to the previous version of the file. The remove-paa-update command uninstalls the updates to the HCL WebSphere Portal server. It then installs and deploys the original PAA file in the wp_profile_root/paa/backup directory.PAA file developer note: Custom code is used to remove updates and restore the previous version of the PAA file. The Solution Installer does not generate code for this task. However, the previously generated code is called from the custom tasks. Previously generated tasks are not run automatically.

Cluster note: Complete these steps on the primary node and then on all additional nodes.
