From 5.1 to 5.2

0. Backup

It's useful to make a backup just in case things go south: (With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version)

cd /home/git/gitlab
sudo -u git -H RAILS_ENV=production bundle exec rake gitlab:backup:create

1. Stop server

sudo service gitlab stop

2. Get latest code

cd /home/git/gitlab
sudo -u git -H git fetch
sudo -u git -H git checkout 5-2-stable

3. Update gitlab-shell

cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v1.4.0

4. Install libs, migrations, etc.

cd /home/git/gitlab

# MySQL
sudo -u git -H bundle install --without development test postgres --deployment

#PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment

sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

sudo -u git -H bundle exec rake assets:precompile RAILS_ENV=production

5. Update config files

• Make /home/git/gitlab/config/gitlab.yml same as https://github.com/gitlabhq/gitlabhq/blob/5-2-stable/config/gitlab.yml.example but with your settings.
• Make /home/git/gitlab/config/puma.rb same as https://github.com/gitlabhq/gitlabhq/blob/5-2-stable/config/puma.rb.example but with your settings.

6. Update Init script

cd /home/git/gitlab
sudo rm /etc/init.d/gitlab
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab 
sudo chmod +x /etc/init.d/gitlab

7. Create uploads directory

cd /home/git/gitlab
sudo -u git -H mkdir public/uploads
sudo chmod -R u+rwX  public/uploads

8. Start application

sudo service gitlab start
sudo service nginx restart

9. Check application status

Check if GitLab and its environment are configured correctly:

sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

To make sure you didn't miss anything run a more thorough check with:

sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations upgrade complete!

Things went south? Revert to previous version (5.1)

1. Revert the code to the previous version

Follow the upgrade guide from 5.0 to 5.1, except for the database migration (The backup is already migrated to the previous version)

2. Restore from the backup:

cd /home/git/gitlab
sudo -u git -H RAILS_ENV=production bundle exec rake gitlab:backup:restore
