Upgrading Evergreen from a 1.2.x release to 1.4.0.7

Install new and upgraded prerequisites. The easiest way to do this is to use the Makefile.install prerequisite installer; it will skip any prerequisites that are already installed on your system. Run the following command as root, where _distribution_ is one of debian or ubuntu:
```
make -f Open-ILS/src/extras/Makefile.install _distribution_
```
Install OpenSRF 1.0.7. See upgrading OpenSRF 0.9 to 1.0 for some gotchas. Otherwise, it's basically:
```
./configure --prefix=/openils --sysconfdir=/openils/conf
make
make install
```

Install Evergreen 1.4.0.7.

./configure --prefix=/openils --sysconfdir=/openils/conf
make
sudo make STAFF_CLIENT_BUILD_ID=rel_1_4_0_7 install
 
# 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
chown -R opensrf:opensrf /openils

From version 1.2 NOTE: it is recommended that you shut down PostgreSQL and make a copy of the data directory in order to restore to Evergreen 1.2 if anything goes wrong

# Upgrading from Evergreen 1.2.3.x:
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.2.3-1.4-upgrade-db.sql
 
# Or from Evergreen 1.2.4.x:
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.2.4-1.4-upgrade-db.sql
 
# and then, for both:
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.2-1.4.0.3-upgrade-db.sql
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.3-1.4.0.4-upgrade-db.sql
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.4-1.4.0.5-upgrade-db.sql
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.5-1.4.0.6-upgrade-db.sql
psql -U evergreen -h localhost -f Open-ILS/src/sql/Pg/1.4.0.6-1.4.0.7-upgrade-db.sql

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:
```
# 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
```
See the OpenSRF install instructions and the Evergreen install instructions for information on setting up a multidomain OpenSRF environment. You will have to define new Jabber users and modify your Jabber configuration file to reflect the additional domains.
Update Apache configuration:
1. Update /etc/apache2/startup.pl with the example from Open-ILS/examples/apache/startup.pl (primarily to add the Vandelay Perl module).
2. Update /etc/apache2/eg_vhost.conf with the example from Open-ILS/examples/apache/eg_vhost.conf for internationalization and JSON gateway format support.
3. Update /etc/apache2/sites-available/eg.conf with the example from Open-ILS/examples/apache/eg.conf for internationalization support in the SlimPAC.
4. Update the cached JavaScript with:
```
sudo -u opensrf /openils/bin/autogen.sh -c /openils/conf/opensrf_core.xml -u
```
