These are instructions to upgrade from Horde 2.2.x to Horde 3.0.  Please
backup your existing data before running any of the steps described below.
You can't use the updated data with your old Horde version anymore.


Configuration files
===================

The configuration files have been changed to XML format.  To generate a valid
configuration file from the XML file, follow the configuration instructions
in the applications' ``docs/INSTALL`` file.


Preferences
===========

The ``last_login`` and ``date_format`` preferences have changed their format
and/or scope.  Just remove all ``last_login`` and ``date_format`` preferences
from the preferences backend.


SQL Backends

A few new tables have been added to Horde.

Execute the provided SQL script to update your data to the new Horde version::

   mysql --user=root --password=<MySQL-root-password> <db name> < scripts/upgrades/2.2_to_3.0.mysql.sql
