gitlab-org--gitlab-foss/doc/update/8.4-to-8.5.md

# From 8.4 to 8.5

### 1. Stop server

    sudo service gitlab stop

### 2. Backup

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

### 3. 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 8-5-stable
```

OR

For GitLab Enterprise Edition:

```bash
sudo -u git -H git checkout 8-5-stable-ee
```

### 4. Update gitlab-shell

```bash
cd /home/git/gitlab-shell
sudo -u git -H git fetch --all
sudo -u git -H git checkout v2.6.10
```

### 5. Update gitlab-workhorse

Install and compile gitlab-workhorse. This requires
[Go 1.5](https://golang.org/dl) which should already be on your system from
GitLab 8.1.

```bash
cd /home/git/gitlab-workhorse
sudo -u git -H git fetch --all
sudo -u git -H git checkout 0.6.4
sudo -u git -H make
```

### 6. 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 postgres development test --deployment

# PostgreSQL installations (note: the line below states '--without mysql')
sudo -u git -H bundle install --without mysql development test --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

```

### 7. Update configuration files

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

There are new configuration options available for [`gitlab.yml`](config/gitlab.yml.example). View them with the command below and apply them manually to your current `gitlab.yml`:

```sh
git diff origin/8-4-stable:config/gitlab.yml.example origin/8-5-stable:config/gitlab.yml.example
```

### 8. Start application

    sudo service gitlab start
    sudo service nginx restart

### 9. 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:

    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations, the upgrade is complete!

## Things went south? Revert to previous version (8.4)

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

Follow the [upgrade guide from 8.3 to 8.4](8.3-to-8.4.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.
