--------------------------
 Upgrading to Horde 3.0.6
--------------------------

If you are no longer able to view attachments in IMP after upgrading Horde to
this or a later version, disable the ``register_globals`` setting in your PHP
configuration or upgrade to IMP 4.0.4 or higher.


------------------------
 Upgrading to Horde 3.0
------------------------

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
