======Upgrading from Evergreen 1.2.3 to 1.2.4======

=====Installing the new version=====

  - Download and unpack http://www.open-ils.org/downloads/Evergreen-ILS-1.2.4.0.tar.gz in a temporary directory.
  - Make a backup copy of all your files, but especially the ''/openils/conf'' directory.
  - Stop Apache.  On some systems this can be accomplished by doing 'sudo service apache2 stop'.
  - Stop Evergreen:<code bash>
su - opensrf
/openils/bin/osrf_ctl.sh -c /openils/conf/opensrf_core.xml -a stop_all</code>  (You may have to change the paths to match your installation.)
  - Perform the [[zzz_archive:server_installation]] steps relevant to your platform; typically you can skip the prerequisites and go directly to the section that includes ''make config'' and ends with ''make install''.  **__WARNING__:**  You will **DESTROY your Evergreen database** if you supply 'openils_all evergreen_core' for the Build_targets part of 'make config'.  Instead, use the following Build_targets: <code>openils_core openils_web openils_reporter openils_client_xul openils_server_xul evergreen_core</code>
  - Start Evergreen: <code>sudo -u opensrf /openils/bin/osrf_ctl.sh -c /openils/conf/opensrf_core.xml -a start_router
sudo -u opensrf /openils/bin/osrf_ctl.sh -c /openils/conf/opensrf_core.xml -a start_perl
sudo -u opensrf /openils/bin/osrf_ctl.sh -c /openils/conf/opensrf_core.xml -a start_c
sudo -u opensrf /openils/bin/autogen.sh -c /openils/conf/opensrf_core.xml -u</code>
  - Start Apache.  On some systems this can be accomplished by doing 'sudo service apache2 start'.

=====Database Schema Upgrade=====

An SQL script is provided to alleviate any need to work with the database by hand.  Database upgrade procedures for at least version 1.2.3.0 must be in place before running this script.  Instructions for upgrading from 1.2.0 or 1.2.1.0 to 1.2.1.1 through 1.2.3.1 can be found [[zzz_archive:upgrading:1.2.2_to_1.2.3|here]].

These instructions assume that PostgreSQL is running on the local machine, there is a database called 'evergreen', a database user called 'evergreen' and a database password of 'password'.  Modify these settings as required.

  - To upgrade the database schema, issue the following commands against the Evergreen database:<code>
 $ cd Evergreen-ILS-1.2.4.0/Open-ILS/src/sql/Pg/
 $ PGUSER=postgres PGHOST=127.0.0.1 psql evergreen -W -f 1.2.3-1.2.4.0-upgrade.sql
   Password: [password]
</code>
