NOTE: This documentation is also available in the Evergreen documentation at http://docs.evergreen-ils.org/1.6/draft/html/upgradingevergreen.html. In github: http://github.com/rsoulliere/Evergreen-DocBook/blob/master/1.6/admin/Upgrading-Evergreen_1.6.xml.

1. Stop Apache.
2. Stop all Evergreen and OpenSRF services. As the opensrf user:

   osrf_ctl.sh -l -a stop_all

3. Install OpenSRF 1.2.2.
4. Download and build Evergreen:
   1. As the opensrf user, download and extract the latest version of Evergreen (http://open-ils.org/downloads/Evergreen-ILS-1.6.0.4.tar.gz):

      wget http://open-ils.org/downloads/Evergreen-ILS-1.6.0.4.tar.gz
      tar xzf Evergreen-ILS-1.6.0.4.tar.gz

   2. As the root user, install the prerequisites. Replace <distribution> below with one of these values for your actual distribution:
      • debian-etch for Debian Etch (4.0)
      • debian-lenny for Debian Lenny
      • ubuntu-hardy for Ubuntu Hardy Heron (8.04)
      • ubuntu-intrepid for Ubuntu Intrepid Ibex (8.10)

        cd /home/opensrf/Evergreen-ILS-1.6.0.4
        make -f Open-ILS/src/extras/Makefile.install <distribution>

   3. As the opensrf user, configure and compile Evergreen:

      cd /home/opensrf/Evergreen-ILS-1.6.0.4
      ./configure --prefix=/openils --sysconfdir=/openils/conf
      make

   4. As the root user, install Evergreen:

      make STAFF_CLIENT_BUILD_ID=rel_1_6_0_4 install

   5. As the opensrf user, update configuration files:

      cd /home/opensrf/Evergreen-ILS-1.6.0.4
      # Build live-db-setup.pl for the cgi-bin bootstrapping scripts
      # and offline-config.pl for the offline staff client data uploader
      sudo perl Open-ILS/src/support-scripts/eg_db_config.pl \
        --create-bootstrap --create-offline --user evergreen --password evergreen \
        --hostname localhost --port 5432 --database evergreen
       
      # Change all files to be owned by the opensrf user/group
      sudo chown -R opensrf:opensrf /openils

5. Upgrade the database:
   1. NOTE: it is recommended that you back up your Evergreen database in order to restore your data if anything goes wrong
   2. Download the billing view hot-fix script.

      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.5-1.6.0.0-upgrade-db.sql evergreen
      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.6.0.0-1.6.0.1-upgrade-db.sql evergreen
      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.6.0.1-1.6.0.2-upgrade-db.sql evergreen
      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.6.0.2-1.6.0.3-upgrade-db.sql evergreen
      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.6.0.3-1.6.0.4-upgrade-db.sql evergreen
      psql -U evergreen -h localhost -f 1.6.0-mmbxs-cleanup.sql evergreen

   3. If you are also upgrading from Postgres 8.2 to Postgres 8.3, you must also run the following script. Do not run this script if you are staying with Postgres 8.2.

      psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/000.english.pg83.fts-config.sql evergreen

6. As the opensrf user, copy /openils/conf/oils_web.xml.example to /openils/conf/oils_web.xml (needed for acquisitions templates)
7. Update opensrf_core.xml and opensrf.xml. A naive way would be to copy the new example files (/openils/conf/opensrf_core.xml.example and /openils/conf/opensrf.xml) and then update the username / password / hostname info and other customizations you might have made. The following step will automatically propagate database usernames and passwords into opensrf.xml (note that this operates on a file already using the 1.6 structure; it will not migrate an existing 1.4 opensrf.xml file to the 1.6 structure):

   # Update opensrf.xml with the database connection info
   sudo perl Open-ILS/src/support-scripts/eg_db_config.pl --update-config \
     --service all --user evergreen --password evergreen --hostname localhost \
     --port 5432 --database evergreen

8. Update Apache configuration:
   1. Update /etc/apache2/startup.pl with the example from Open-ILS/examples/apache/startup.pl
   2. Update /etc/apache2/eg_vhost.conf with the example from Open-ILS/examples/apache/eg_vhost.conf
   3. Update /etc/apache2/sites-available/eg.conf with the example from Open-ILS/examples/apache/eg.conf
9. Start all Evergreen and OpenSRF services. As the opensrf user:

   osrf_ctl.sh -l -a start_all

10. Start Apache.
11. As the opensrf user, run autogen to refresh the static organizational data files:

    cd /openils/bin
    ./autogen.sh -c /openils/conf/opensrf_core.xml -u

12. Troubleshooting:

If you run into errors, see: Troubleshooting: Checking for Errors for help finding errors in the log files. You may also ask the evergreen community using the mailing lists. Including error information from the logs will be extremely helpful when seeking assistance.

In some cases, you may upgrade OpenSRF to version 1.2 instead of installing from scratch. To upgrade:

1. Go to the instructions for installing OpenSRF 1.2.2 and complete steps 2, 3, (4 I, II, III b) and 5
2. Restart OpenSRF and test connections using srfsh.
