-== The basic theory ==
+This file provides an overview of the MediaWiki upgrade process. For help with
+specific problems, check
-Generally, within a stable release series (e.g. 1.4.0, 1.4.1, etc) there
-are no required database changes, and upgrading should require no more
-than copying the new source files over the old ones.
+* the documentation at http://meta.wikimedia.org
+* the documentation at http://www.mediawiki.org
+* the mediawiki-l mailing list archive at
+ http://mail.wikipedia.org/pipermail/mediawiki-l
+* the bug tracker at http://bugzilla.wikimedia.org
-If there are larger changes, such as upgrading from one release series
-to another (e.g. from 1.3.12 to 1.4.3), then you may need to update the
-database schema and configuration.
+for information and workarounds to common issues.
-Basically, to upgrade a wiki you:
-* Back up your data! (See Backups! below)
-* Extract the new archive. If you can do this in a clean directory that's
- great, but it should work to extract over the old files too. This may
- be easier if you have images etc in place and don't want to move them
- around, but remember to back up first!
-* Run the installer to upgrade the database schema (if necessary).
+== Overview ==
+Documentation on upgrading to 1.7 can also be found at
+http://www.mediawiki.org/wiki/Manual:Upgrading_to_1.7.
-== IMPORTANT: Upgrading to 1.5 ==
+=== Consult the release notes ===
+
+Before doing anything, stop and consult the release notes supplied with the new
+version of the software. This 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.
+
+Refer to the MySQL documentation for information on backing up a database. For
+information on making copies of files, consult the documentation for your
+operating system.
+
+=== Perform the file upgrade ===
+
+Having downloaded the desired new version of the software, either as a package
+from SourceForge, or via an export from Subversion, decompress the files as
+needed, and replace the existing MediaWiki files with the new.
+
+You should preserve:
+
+* The LocalSettings.php file
+* The AdminSettings.php file, where it exists
+* The extensions directory
+* The images directory
+
+If using an alternative uploads directory, preserve this; and if using custom
+skins, preserve these too. The core code is now updated.
+
+=== 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 $wgEnableUploads in later versions. When upgrading, consult the release
+notes to check for configuration changes which would alter the expected
+behaviour of MediaWiki.
+
+=== Test ===
+
+It makes sense to test your wiki immediately following any kind of maintenance
+procedure, and especially after upgrading; check that page views and edits work
+normally and that special pages continue to function, etc. and correct errors
+and quirks which reveal themselves.
+
+== Upgrading from 1.6 wikis ==
+
+$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.
-DO NOT ATTEMPT TO UPGRADE A LIVE, PUBLIC SITE TO 1.5 AT THIS TIME.
-NEVER EVER ATTEMPT TO PERFORM AN UPGRADE WITHOUT BACKING UP FIRST!
-
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, however the updater has not yet been updated to support
-this automatically.
+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 chagned 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. To emulate the old effect of setting:
+ $wgWhitelistAccount['user'] = 0;
+set:
+ $wgGroupPermissions['*']['createaccount'] = false;
+
+$wgWhitelistEdit has been replaced by the 'edit' permission key.
+To emulate the old effect of setting:
+ $wgWhitelistEdit = true;
+set:
+ $wgGroupPermissions['*']['edit'] = false;
+
+If $wgWhitelistRead is set, you must also disable the 'read' permission
+for it to take affect on anonymous users:
+ $wgWhitelistRead = array( "Main Page", "Special:Userlogin" );
+ $wgGroupPermissions['*']['read'] = false;
+
+Note that you can disable/enable several other permissions by modifying
+this configuration array in your LocalSettings.php; see DefaultSettings.php
+for the complete default permission set.
+
+If using Memcached, you must enabled it differently now:
+ $wgUseMemCached = true;
+should be replaced with:
+ $wgMainCacheType = CACHE_MEMCACHED;
+
