You can upgrade Arbortext Editor, Arbortext Styler, and Arbortext Publishing Engine from version 8.2.2.0 to 8.2.3.0.

However, upgrade from an installation earlier than 8.2.2.0 is not supported. You must uninstall the previous version before installing 8.2.3.0. You must copy any customizations to a temporary folder before uninstalling.
