GitLab Documentation

From Community Edition 8.15 to Enterprise Edition 8.15

This guide assumes you have a correctly configured and tested installation of GitLab Community Edition 8.15. If you run into any trouble or if you have any questions please contact us at

0. Backup

Make a backup just in case something goes wrong:

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

For installations using MySQL, this may require granting "LOCK TABLES" privileges to the GitLab user on the database version.

1. Stop server

sudo service gitlab stop

2. Get the EE code

cd /home/git/gitlab
sudo -u git -H git remote add -f ee
sudo -u git -H git checkout 8-15-stable-ee

3. Install libs, migrations, etc.

cd /home/git/gitlab

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

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

4. Start application

sudo service gitlab start
sudo service nginx restart

5. 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 (Community Edition 8.15)

1. Revert the code to the previous version

cd /home/git/gitlab
sudo -u git -H git checkout 8-15-stable

2. Restore from the backup

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