For help with +specific problems, check + +* the documentation at http://www.mediawiki.org +* the mediawiki-l mailing list archive at + http://lists.wikimedia.org/pipermail/mediawiki-l/ +* the bug tracker at https://bugzilla.wikimedia.org + +for information and workarounds to common issues. + +== Overview == + +Comprehensive documentation on upgrading to the latest version of the software +is available at http://www.mediawiki.org/wiki/Manual:Upgrading. + +=== Consult the release notes === + +Before doing anything, stop and consult the release notes supplied with the new +version of the software. 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 upgrade 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, AdminSettings.php file (if present), 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 === + +You will need an AdminSettings.php file set up in the correct format; see +AdminSettings.sample in the wiki root for more information and examples. + +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 $wgEnableUploads in later versions. When upgrading, consult the release +notes to check for configuration changes which would alter the expected +behaviour of MediaWiki. + +=== Check installed extensions === +In MediaWiki 1.14 some extensions are migrated into the core. Please see the +RELEASE-NOTES section "Migrated extensions" and disable these extensions in your +localSettings.php + +=== Test === + +It makes sense to test your wiki immediately following any kind of maintenance +procedure, and especially after upgrading; check that page views and edits work +normally and that special pages continue to function, etc. and correct errors +and quirks which reveal themselves. + +You should also test any extensions, and upgrade these if necessary. + +== Upgrading from 1.8 wikis == + +MediaWiki 1.9 and later no longer keep default localized message text +in the database; 'MediaWiki:'-namespace pages that do not exist in the +database are simply transparently filled-in on demand. + +The upgrade process will delete any 'MediaWiki:' pages which are left +in the default state (last edited by 'MediaWiki default'). This may +take a few moments, similar to the old initial setup. + +Note that the large number of deletions may cause older edits to expire +from the list on Special:Recentchanges, although the deletions themselves +will be hidden by default. (Click "show bot edits" to list them.) + + +See RELEASE-NOTES for more details about new and changed options. + + +== Upgrading from 1.7 wikis == + +$wgDefaultUserOptions now contains all the defaults, not only overrides. +If you're setting this as a complete array(), you may need to change it +to set only specific items as recommended in DefaultSettings.php. + +== Upgrading from 1.6 wikis == + +$wgLocalTZoffset was in hours, it is now using minutes. +Link autonumbering got fixed (#5918) for protocols other than http. + - 'irc://irc.server.tld/' render as a link with a chat icon + - '[irc://irc.server.tld]' render as an autonumbered link: [1] + +== Upgrading from pre-1.5 wikis == + +Major changes have been made to the schema from 1.4.x. The updater +has not been fully tested for all conditions, and might well break. + +On a large site, the schema update might take a long time. It might +explode, or leave your database half-done or otherwise badly hurting. + +Among other changes, note that Latin-1 encoding (ISO-8859-1) is +no longer supported. Latin-1 wikis will need to be upgraded to +UTF-8; an experimental command-line upgrade helper script, +'upgrade1_5.php', can do this -- run it prior to 'update.php' or +the web upgrader. + +If you absolutely cannot make the UTF-8 upgrade work, you can try +doing it by hand: dump your old database, convert the dump file +using iconv as described here: +http://portal.suse.com/sdb/en/2004/05/jbartsh_utf-8.html +and then reimport it. You can also convert filenames using convmv, +but note that the old directory hashes will no longer be valid, +so you will also have to move them to new destinations. + +Message changes: +* A number of additional UI messages have been changed from HTML to + wikitext, and will need to be manually fixed if customized. + +=== Configuration changes from 1.4.x: === + +$wgDisableUploads has been replaced with $wgEnableUploads. + +$wgWhitelistAccount has been replaced by the 'createaccount' permission +key in $wgGroupPermissions.
