# PostgreSQL installations (note: the line below states '--without ... mysql')

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/7-4-stable:config/gitlab.yml.example origin/7-5-stable:config/gitlab.yml.example
```

#### Change Nginx settings

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

### 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 (7.4)

### 1. Revert the code to the previous version
Follow the [upgrade guide from 7.3 to 7.4](7.3-to-7.4.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
```
If you have more than one backup *.tar file(s) please add `BACKUP=timestamp_of_backup` to the command above.
