Upgrading to vmm 0.6.x

======================

This document describes the procedure to upgrade a vmm-0.5.2 installation

to version 0.6.x

If you still have installed vmm-0.4/vmm-0.4-r41 you have to proceed this

step first:

 ‣ :doc:`0.4.x-0.5`

Upgrading from vmm-0.5.2

------------------------

Stop Postfix and Dovecot

^^^^^^^^^^^^^^^^^^^^^^^^

Before updating your database layout you have to stop Postfix and Dovecot.

.. code-block:: console

 root@host:~# /etc/init.d/postfix stop

 Stopping Postfix Mail Transport Agent: postfix.

 root@host:~# /etc/init.d/dovecot stop

 Stopping IMAP/POP3 mail server: dovecot.

Create a database backup

^^^^^^^^^^^^^^^^^^^^^^^^

It is always wise to back up your database from time to time.

Particularly with regard to an impending structure modification.

Example: Backing up the `mailsys` database with pg_dump_.

.. code-block:: console

 user@host:~$ pg_dump -h localhost -U vmm -W mailsys > mailsys-0.5.2.sql

Database update

^^^^^^^^^^^^^^^

Connect as your `vmm` database user to your database.

.. code-block:: console

 user@host:~$ psql mailsys vmm -W -h localhost

In the PostgreSQL interactive terminal you have to run one of the following

commands to perform the update.

Dovecot v1.2.x/v2.0.x/v2.1.x

""""""""""""""""""""""""""""

.. code-block:: postgresql-console

 mailsys=> \i /path/to/vmm-0.6.0/pgsql/update_tables_0.5.x-0.6-dovecot-1.2.x.pgsql

 mailsys=> \q

Dovecot v1.0.x/v1.1.x

"""""""""""""""""""""

.. code-block:: postgresql-console

 mailsys=> \i /path/to/vmm-0.6.0/pgsql/update_tables_0.5.x-0.6.pgsql

 mailsys=> \q

Set database permissions

^^^^^^^^^^^^^^^^^^^^^^^^

.. include:: ../pgsql_set_permissionspermissions.rst

Start Dovecot and Postfix again

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. warning:: All the views (*dovecot_…* and *postfix_…*) have been

   replaced by database functions.

   So you have to adjust all your ``postfix/pgsql-*.cf`` files and also your

   ``/etc/dovecot/dovecot-sql.conf`` or ``/etc/dovecot/dovecot-sql.conf.ext``.

   See the `vmm-0.6.0/postfix/pgsql-*.cf` files and

   :ref:`Dovecot configuration <dovecot-sql-conf-ext>`/`dovecot-sql.conf.ext`

   or :ref:`Dovecot configuration <dovecot-sql-conf>`/`dovecot-sql-conf`.

After a successfully update start Dovecot and Postfix again.

.. code-block:: console

 root@host:~# /etc/init.d/dovecot start

 Starting IMAP/POP3 mail server: dovecot.

 root@host:~# /etc/init.d/postfix start

 Starting Postfix Mail Transport Agent: postfix.

Upgrade vmm

^^^^^^^^^^^

Finally execute the :file:`upgrade.sh` script.

This will install the new code and also update your :file:`vmm.cfg`.

.. code-block:: console

 root@host:~# cd /path/to/vmm-0.6.0

 root@host:/path/to/vmm-0.6.0# ./upgrade.sh

 Please have a look at your configuration: /usr/local/etc/vmm.cfg
