You can upgrade a previous version of Transformer to a new version. You can upgrade an installation from the tarball or from the RPM package.

The upgrade process for Transformer involves installing the new version. You then configure the new version to use the new configuration files but the previous data, log, and resource files. That way, the new version has access to the new configuration files required for Transformer to start or function properly, and has access to the data, log, and resource files created in the previous version.

In some situations, you must complete pre and post upgrade tasks.
