gitlab-org--gitlab-foss/doc/update/7.5-to-7.6.md

# From 7.5 to 7.6

### 0. Stop server

    sudo service gitlab stop

### 1. Backup

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

### 2. Get latest code

```bash
sudo -u git -H git fetch --all
sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
```

For GitLab Community Edition:

```bash
sudo -u git -H git checkout 7-6-stable
```

OR

For GitLab Enterprise Edition:

```bash
sudo -u git -H git checkout 7-6-stable-ee
```

### 3. Update gitlab-shell

```bash
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v2.4.0
```

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

```bash
sudo apt-get install libkrb5-dev

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
```

### 5. Update config files

#### New configuration options for `gitlab.yml`

There are new configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them to your current `gitlab.yml`.

```
git diff origin/7-5-stable:config/gitlab.yml.example origin/7-6-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

#### Setup time zone (optional)

Consider setting the time zone in `gitlab.yml` otherwise GitLab will default to UTC. If you set a time zone previously in [`application.rb`][app] (unlikely), unset it.

### 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 (7.5)

### 1. Revert the code to the previous version
Follow the [upgrade guide from 7.4 to 7.5](7.4-to-7.5.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.
