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

For example from 7.14.0 to 7.14.3, also see the [semantic versioning specification](http://semver.org/).

### 0. Backup

It's useful to make a backup just in case things go south:
(With MySQL, this may require granting "LOCK TABLES" privileges to the GitLab
user on the database version)

```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 for the stable branch

In the commands below, replace `LATEST_TAG` with the latest GitLab tag you want
to update to, for example `v8.0.3`. Use `git tag -l 'v*.[0-9]' --sort='v:refname'`
to see a list of all tags. Make sure to update patch versions only (check your
current version with `cat VERSION`).

```bash
cd /home/git/gitlab
sudo -u git -H git fetch --all
sudo -u git -H git checkout -- Gemfile.lock db/schema.rb
sudo -u git -H git checkout LATEST_TAG -b LATEST_TAG
```

### 3. Update gitlab-shell to the corresponding version

```bash
cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v`cat /home/git/gitlab/GITLAB_SHELL_VERSION` -b v`cat /home/git/gitlab/GITLAB_SHELL_VERSION`
```

### 4. Update gitlab-workhorse to the corresponding version

```bash
cd /home/git/gitlab-workhorse
sudo -u git -H git fetch
sudo -u git -H git checkout `cat /home/git/gitlab/GITLAB_WORKHORSE_VERSION` -b `cat /home/git/gitlab/GITLAB_WORKHORSE_VERSION`
```

### 5. Install libs, migrations, etc.

```bash
cd /home/git/gitlab

# PostgreSQL
sudo -u git -H bundle install --without development test mysql --deployment

# MySQL
sudo -u git -H bundle install --without development test postgres --deployment

sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
```

### 6. Start application

```bash
sudo service gitlab start
sudo service nginx restart
```

### 7. Check application status

Check if GitLab and its environment are configured correctly:

```bash
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:

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

If all items are green, then congratulations upgrade complete!
