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.
For a major and minor release, the installer prompts whether you wish to upgrade, and informs you if incompatible products are on your system. If you proceed, major or minor releases are installed under a new directory that is named using the major or minor release numbers.
For example, if you have installed the 5.3.0 release and are upgrading to a 5.4.0 minor release, it will be installed under the 5.4 directory. This allows both the 5.3 and 5.4 releases to coexist on the same machine.
If you are upgrading TIBCO BusinessEvents, it is strongly recommended that you uninstall the earlier version of the product first and perform a fresh installation (full product installers only).
