  To use the Grouper installer, see the "Grouper Installer" training video and this wiki page.

Here is a movie demonstrating the  Grouper upgrader, which is new as of Grouper 2.2.1

     For a minor upgrade, see the "Grouper Minor Upgrade" training videoNote: The upgrade to Grouper 2.2  is not a minor upgrade, so there are additional steps, particularly updating the database and running the post install gsh script.  Also, much of the video talks about merging configuration files, and that has changed with Grouper 2.2. See the Upgrade Instructions. The parts of the video on how to rebuild the UI/WS are still relevant and helpful.
