From 7.5 to 7.6

0. Stop server

sudo service gitlab stop

1. Backup

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

2. Get latest code

sudo -u git -H git fetch --all
sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically

For GitLab Community Edition:

sudo -u git -H git checkout 7-6-stable

For GitLab Enterprise Edition:

sudo -u git -H git checkout 7-6-stable-ee

3. Update gitlab-shell

cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v2.4.0

4. Install libs, migrations, etc.

sudo apt-get install libkrb5-dev

cd /home/git/gitlab

# MySQL installations (note: the line below states '--without ... postgres')
sudo -u git -H bundle install --without development test postgres --deployment

# PostgreSQL installations (note: the line below states '--without ... mysql')
sudo -u git -H bundle install --without development test mysql --deployment

# Run database migrations
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

# Clean up assets and cache
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production

# Update init.d script
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab

5. Update config files

New configuration options for `gitlab.yml`

There are new configuration options available for gitlab.yml. View them with the command below and apply them to your current gitlab.yml.

git diff origin/7-5-stable:config/gitlab.yml.example origin/7-6-stable:config/gitlab.yml.example

Change Nginx settings

HTTP setups: Make /etc/nginx/sites-available/gitlab the same as lib/support/nginx/gitlab but with your settings
HTTPS setups: Make /etc/nginx/sites-available/gitlab-ssl the same as lib/support/nginx/gitlab-ssl but with your setting

Setup time zone (optional)

Consider setting the time zone in gitlab.yml otherwise GitLab will default to UTC. If you set a time zone previously in application.rb (unlikely), unset it.

6. Start application

sudo service gitlab start
sudo service nginx restart

7. 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 is complete!

Things went south? Revert to previous version (7.5)

1. Revert the code to the previous version

Follow the upgrade guide from 7.4 to 7.5, 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 bundle exec rake gitlab:backup:restore RAILS_ENV=production

If you have more than one backup *.tar file(s) please add BACKUP=timestamp_of_backup to the command above.
