These detail bug fixes, new features and functionality, +and any particular points that may need to be noted during the upgrade +procedure. + +=== Backup first === + +It is imperative that, prior to attempting an upgrade of the database schema, +you take a complete backup of your wiki database and files and verify it. While +the upgrade scripts are somewhat robust, there is no guarantee that things will +not fail, leaving the database in an inconsistent state. + +http://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki provides an overview of +the backup process. You should also refer to the documentation for your +database management system for information on backing up a database, and to +your operating system documentation for information on making copies of files. + +=== Perform the file upgrade === + +Download the files for the new version of the software. These are available +as a compressed "tar" archive from the Wikimedia Download Service +(http://download.wikimedia.org/mediawiki). + +You can also obtain the new files directly from our Subversion source code +repository, via a checkout or export operation. + +Replace the existing MediaWiki files with the new. You should preserve the +LocalSettings.php file and the "extensions" and "images" directories. + +Depending upon your configuration, you may also need to preserve additional +directories, including a custom upload directory ($wgUploadDirectory), +deleted file archives, and any custom skins. + +=== Perform the database upgrade === + +==== From the web ==== + +If you browse to the web-based installation script (usually at +/mw-config/index.php) from your wiki installation you can follow the script and +upgrade your database in place. + +==== From the command line ==== + +From the command line, browse to the "maintenance" directory and run the +update.php script to check and update the schema. This will insert missing +tables, update existing tables, and move data around as needed. In most cases, +this is successful and nothing further needs to be done. + +=== Check configuration settings === + +The names of configuration variables, and their default values and purposes, +can change between release branches, e.g. $wgDisableUploads in 1.4 is replaced +with $wgEnableUploads in later versions. When upgrading, consult the release +notes to check for configuration changes which would alter the expected +behaviour of MediaWiki. + +=== Check installed extensions === + +Extensions usually need to be upgraded at the same time as the MediaWiki core. + +In MediaWiki 1.14 some extensions were migrated into the core. Please see the +HISTORY section "Migrated extensions" and disable these extensions in your +LocalSettings.php + +=== Test === + +It makes sense to test your wiki immediately following any kind of maintenance +procedure, and especially after upgrading; check that page views and edits work +normally and that special pages continue to function, etc. and correct errors +and quirks which reveal themselves. + +You should also test any extensions, and upgrade these if necessary. + +== Upgrading from 1.16 or earlier == + +If you have a Chinese or Japanese wiki ($wgLanguageCode is set to one +of "zh", "ja", or "yue") and you are using MySQL fulltext search, you +will probably want to update the search index. + +In the "maintenance" directory, run the updateDoubleWidthSearch.php +script. This will update the searchindex table for those pages that +contain double-byte latin characters. + +== Upgrading from 1.8 or earlier == + +MediaWiki 1.9 and later no longer keep default localized message text +in the database; 'MediaWiki:'-namespace pages that do not exist in the +database are simply transparently filled-in on demand. + +The upgrade process will delete any 'MediaWiki:' pages which are left +in the default state (last edited by 'MediaWiki default'). This may +take a few moments, similar to the old initial setup. + +Note that the large number of deletions may cause older edits to expire +from the list on Special:Recentchanges, although the deletions themselves +will be hidden by default.
