# From 6.8 to 6.9

### 0. Backup

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

### 1. Stop server

```bash
sudo service gitlab stop
```

### 2. Get latest code

```bash
cd /home/git/gitlab
sudo -u git -H git fetch --all
```

For Gitlab Community Edition:

```bash
sudo -u git -H git checkout 6-9-stable
```

OR

For GitLab Enterprise Edition:

```bash
sudo -u git -H git checkout 6-9-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 v1.9.4
```

### 4. Install libs, migrations, etc.

```bash
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
```

### 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 if desired.

```
git diff 6-8-stable:config/gitlab.yml.example 6-9-stable:config/gitlab.yml.example
```

### 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 (6.8)

### 1. Revert the code to the previous version
Follow the [`upgrade guide from 6.7 to 6.8`](6.7-to-6.8.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.
