# From 6.2 to 6.3 *Make sure you view this [upgrade guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update/6.2-to-6.3.md) for the most up to date instructions.* **Requires version: 6.1 or 6.2.** ## 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) ```bash cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production ``` ## 1. Stop server sudo service gitlab stop ## 2. Get latest code ```bash cd /home/git/gitlab sudo -u git -H git fetch --all sudo -u git -H git checkout 6-3-stable # For GitLab Enterprise Edition: sudo -u git -H git checkout 6-3-stable-ee ``` ## 3. Update gitlab-shell (and its config) ```bash cd /home/git/gitlab-shell sudo -u git -H git fetch sudo -u git -H git checkout v1.7.9 # Addresses multiple critical security vulnerabilities ``` The gitlab-shell config changed recently, so check for config file changes and make `/home/git/gitlab-shell/config.yml` the same as <https://github.com/gitlabhq/gitlab-shell/blob/master/config.yml.example> ## 4. Install libs, migrations, etc. ```bash cd /home/git/gitlab # The Modernizr gem was yanked from RubyGems. It is required for GitLab >= 2.8.0 # Edit `Gemfile` and change `gem "modernizr", "2.5.3"` to # `gem "modernizr-rails", "2.7.1"`` sudo -u git -H vim Gemfile # MySQL # Run a bundle install without deployment to generate the new Gemfile sudo -u git -H bundle install --without development test postgres --no-deployment # Install libs (with deployment this time) sudo -u git -H bundle install --without development test postgres --deployment # PostgreSQL # Run a bundle install without deployment to generate the new Gemfile sudo -u git -H bundle install --without development test mysql --no-deployment # Install libs (with deployment this time) sudo -u git -H bundle install --without development test mysql --deployment # Both MySQL and PostgreSQL # 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 ``` ## 5. Update config files TIP: to see what changed in gitlab.yml.example in this release use next command: ``` git diff 6-2-stable:config/gitlab.yml.example 6-3-stable:config/gitlab.yml.example ``` - Make `/home/git/gitlab/config/gitlab.yml` same as https://gitlab.com/gitlab-org/gitlab-ce/blob/6-3-stable/config/gitlab.yml.example but with your settings. - Make `/home/git/gitlab/config/unicorn.rb` same as https://gitlab.com/gitlab-org/gitlab-ce/blob/6-3-stable/config/unicorn.rb.example but with your settings. ```bash # Copy rack attack middleware config cd /home/git/gitlab sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb ``` ## 6. Update Init script ```bash sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab ``` ## 7. Start application sudo service gitlab start sudo service nginx restart ## 8. 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 (6.2) ### 1. Revert the code to the previous version Follow the [upgrade guide from 6.1 to 6.2](6.1-to-6.2.md), except for the database migration (the backup is already migrated to the previous version). ### 2. Restore from the backup: ```bash cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production ```
