Software from TIBCO uses three numbers to indicate whether the release is major, minor or a patch. For example, 5.0.0 indicates a major release, 5.4.0 indicates a minor release and 5.3.3 indicates a service pack release.
The installer for a service pack release performs an automatic upgrade. For example, the installer automatically upgrades TRA 5.3.0 to 5.3.1 by overwriting the contents of the 5.3 directory.
If you are upgrading BusinessEvents, it is strongly recommended that you uninstall the earlier version of the product first and perform a fresh installation (full product installers only).
