# From 6.7 to 6.8
*Make sure you view this [upgrade guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update/6.7-to-6.8.md) for the most up to date instructions.*

## 0. Backup

```bash
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 6-8-stable
```

OR

For GitLab Enterprise Edition:

```bash
sudo -u git -H git checkout 6-8-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 v1.9.3
```

## 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

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

# Close access to gitlab-satellites for others
sudo chmod u+rwx,g=rx,o-rwx /home/git/gitlab-satellites
```

## 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 6-7-stable:config/gitlab.yml.example 6-8-stable:config/gitlab.yml.example
```

### MySQL? Remove reaping frequency

If you are using MySQL as a database, remove `reaping_frequency` from you database.yml to prevent crashes. [Relevant commit](https://gitlab.com/gitlab-org/gitlab-ce/commit/5163a8fcb9cfd63435560fda00173b76df2ccc93).

### HTTPS? Disable gzip

If you are using HTTPS, disable gzip as in [this commit](https://gitlab.com/gitlab-org/gitlab-ce/commit/563fec734912d81cd7caea6fa8ec2b397fb72a9b) to prevent BREACH attacks.

### Turn on asset compression

To improve performance, enable gzip asset compression as seen [in this commit](https://gitlab.com/gitlab-org/gitlab-ce/commit/8af94ed75505f0253823b9b2d44320fecea5b5fb).

## 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 (6.7)

### 1. Revert the code to the previous version

Follow the [upgrade guide from 6.6 to 6.7](6.6-to-6.7.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.
