+
−
+
−    * stop Postfix and Dovecot
+
−    * backup/dump your database.
+
−    * backup/dump your database!
+
−
+
−    * start psql and connect to the appropriate database
+
−      (ex. psql mailsys vmm -W -h 127.0.0.1)
+
−    * update the database,
+
−      - Dovecot < 1.2.0
+
−	\i vmm-x.y.z/pgsql/update_tables_0.5.x-0.6.pgsql
+
−      - Dovecot >= 1.2.0, 2.0.0 and 2.1.0
+
−	\i vmm-x.y.z/pgsql/update_tables_0.5.x-0.6-dovecot-1.2.x.pgsql
+
−    * Set database permissions.
+
−      (see python set-permissions.py -h for details)
+
−      python vmm-x.y.z/pgsql/set-permissions.py -a -H 127.0.0.1 -U vmm

−    /!\ Important note /!\
+
−
+
−    All the views (dovecot_* and postfix_*) have been replaced by database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-x.y.z postfix/pgsql-*.cf files and INSTALL/Configure.Dovecot_2
+
−    files for the new query.)
+
−
+
−
+
−    * execute upgrade.sh
+
−      This will also upgrade your vmm.cfg and apply the following modifications:
