Install a New UI Release
QAD highly recommends you deploy only the components included with the latest QAD UI release. The latest release always contains the most recent component versions, patches, and performance improvements. Review Release Notes on the QAD UI media to see if any updated .NET UI system components have been included.
Consider the following items before you install a new release:
• Some releases cannot be installed directly into directories that contain any components from a previous UI version. Install QAD .NET UI into new directories that do not contain components from a previous release.
Always check the release notes to see if this condition applies to the release you plan to implement.
• The installation process installs updated code; therefore, the installation directory must be placed at the front of all your system PROPATHs.
• The latest QAD-optimized Tomcat version is always included on the QAD UI media. Always install the new version. This can be done manually or automatically using the Perl installation tools.
• If the client Java version has not been updated, initial client startup after setting up the new QAD .NET UI might require a Java download.
• The latest QAD-tested version of the SVG plug-in is always included on the QAD UI media. Process Editor client machines need to download the new plug-in.
• The Tomcat server cache must be cleared after installing a new release. You do not have to manually clear the client cache. When you install a new release, new files are automatically cached by the client. The old files are deleted automatically based on client browser history settings.
• After a release upgrade, client machine performance may be slightly affected while new HTML pages are generated on the server and cached locally on each client. This only affects the initial client sessions while new pages are being cached.
• Process maps are located in /WEB-INF/pronav/xml in the Tomcat webapps directory. If you are using a release that requires a complete new installation, copy the existing process maps from the previous system to the new system directory structure.
