# From 6.6 to 6.7
*Make sure you view this [upgrade guide from the `master` branch](../../../master/doc/update/6.6-to-6.7.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

    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 6-7-stable
```

OR

For GitLab Enterprise Edition:

```bash
sudo -u git -H git checkout 6-7-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 v1.9.1
```

## 4. Install libs, migrations, etc.

```bash
cd /home/git/gitlab

# 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

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

# Update the logrotate configuration (keep logs for 90 days instead of 52 weeks)
sudo cp lib/support/logrotate/gitlab /etc/logrotate.d/gitlab

# Compress existing .log.1 files because we turned off delaycompress in logrotate
sudo -u git -H gzip /home/git/gitlab/log/*.log.1
sudo -u git -H gzip /home/git/gitlab-shell/gitlab-shell.log.1

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

# Add directory for uploads
sudo -u git -H mkdir -p /home/git/gitlab/public/uploads
```

## 5. Start application

    sudo service gitlab start
    sudo service nginx restart

## 6. 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 (6.6)

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

Follow the [upgrade guide from 6.5 to 6.6](6.5-to-6.6.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.
