h1. Migration of foreman 0.4.3 to foreman 1.4
Unfortunately the upgrade of foreman 0.4.3 isn't as easy as upgrading the packages, since their are some problems avoiding a working database migration. The following process has been developed and tested on a Debian Squeeze setup with the help of Greg Sutcliffe (gwmngilfen) and should work for other setups, too:
# Upgrade the system to Debian Wheezy in case you haven't already
# Create a full dump of the database (important step! without it the update
WILL fail)
sudo -u postgres pg_dump foreman > /root/foreman_0.4.2.sql
# Drop the foreman database and remove foreman
sudo -u postgres dropdb foreman
sudo dpkg -r foreman foreman-pgsql foreman-proxy
# Backup /etc/foreman
sudo cp -r /etc/foreman /root/etc_foreman_0.4.2
# Add foreman sources.list entries
cat <<EOF>/etc/apt/sources.list.d/foreman.list
deb http://deb.theforeman.org/ wheezy stable
deb http://deb.theforeman.org/ wheezy 1.2
deb http://deb.theforeman.org/ squeeze 1.2

# Install some packages:
apt-get install build-essential ruby1.9.1-dev
# Install foreman-installer package and run the forema installer.
sudo foreman-installer
Should end in a working, clean installation of 1.4
(otherwise fix all problems, because thats where we want to get)
One possible helpful command to that extend could be:
cd /usr/share/foreman; bundle install
followed by
dpkg --configure -a
If dpkg is successful foreman-installer will be successful too.
It can be required to re-run the foreman-installer, though.
# Drop the 1.4 database and recreate it with the 0.4.2 dump
sudo -u postgres dropdb foreman
sudo -u postgres createdb foreman
Populate it with the 0.4.2 backup
sudo -u postgres psql foreman < /root/foreman_0.4.2.sql
# Downgrade foreman to 1.1.1+debian1
apt-get install foreman=1.1.1+debian1 foreman-postgresql=1.1.1+debian1
# Open /usr/share/foreman/lib/foreman/default_settings/loader.rb and comment the set commands for the oauth_keys (line 79-82), be careful to keep the "[" in front of line 79.
# Apply the patch from https://github.com/theforeman/foreman/commit/fb0998a0ecf9e78822d321044b8eed89cbe7a9f9.patch
(the test/lib/puppet_setting_test.rb part in the patch can be deleted; it does not apply since this is an install and not the source tree)
# TRUNCATE audits table in foremann (yeah, thats neccessary - sorry)
sudo -u foreman psql foreman -c 'TRUNCATE audits'
# Execute the migration scripts:
sudo -u foreman bundle exec rake db:migrate RAILS_ENV=production --trace
# Now upgrade to 1.4.1 again
sudo apt-get install foreman=1.4.1-1 foreman-postgresql=1.4.1-1
# Add label column to hostgroup table:
sudo -u foreman psql foreman -c 'ALTER TABLE hostgroups ADD label character varying(255);'
# Comment line 3 and 4 in /usr/share/foreman/db/migrate/20130924145800_remove_unused_role_fields.rb:
# Run db migration scripts from 1.4:
foreman-rake db:migrate
# Revert the modification of 20130924145800_remove_unused_role_fields.rb
# Done!
