			@title Upgrading Schema
			@group config

			This document descibes how to upgrade the database schema.

			= Prerequisites =

			This document assumes you've already initialized the MySQL database and
			configured your Phabricator environment. If you haven't, see
			@{article:Configuration Guide}.

			= Loading patches =

			If you are doing this for the first time to a freshly installed MySQL database,
			run the following command:

			PHABRICATOR_ENV=<your_config> php path/to/phabricator/scripts/sql/upgrade_schema.php 0

			This will install all the patches starting from 0. Running this script will
			store the information of the latest installed patch in the Phabricator database.
			Next time you want to upgrade your schema, just run:

			PHABRICATOR_ENV=<your_config> php path/to/phabricator/scripts/sql/upgrade_schema.php

			This will install all the patches that are new since the last time you ran
			this script.

			If you need to upgrade the schema starting from a specific patch, just run:

			PHABRICATOR_ENV=<your_config> php path/to/phabricator/scripts/sql/upgrade_schema.php <patch_number>

			However, this isn't usually needed.
