Look in docs/UPGRADING . For example in horde/docs/UPGRADING


Upgrading Horde from 2.x to 3.0.x
=================================


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
