-
-=== Web installer ===
-
-You can use the web-based installer wizard if you first remove the
-LocalSettings.php file; be sure to give the installer the same
-information as you did on the original install (language/encoding,
-database name, password, etc). This will also generate a fresh
-LocalSettings.php, which you may need to customize.
-
-You may change some settings during the install, but be very careful!
-Changing the encoding in particular will generally leave you with a
-lot of corrupt pages, particularly if your wiki is not in English.
-
-=== Command-line upgrade ===
-
-Additionally, as of 1.4.0 you can run an in-place upgrade script from
-the command line, keeping your existing LocalSettings.php. This requires
-that you set $wgDBadminuser and $wgDBadminpassword with an appropriate
-database user and password with privileges to modify the database structure.
-
-Once the new files are in place, go into the maintenance subdirectory and
-run the script:
-
- php update.php
-
-See caveats below on upgrading from 1.3.x or earlier.
-
-
-== Backups! ==
-
-To upgrade an existing MediaWiki installation, first BACK UP YOUR WIKI!
-If something goes wrong, you want to be able to start again.
-
-Your image files, configuration, etc can simply be copied or archived as
-you would any other files. (Make sure that the contents of your
-LocalSettings.php are not accidentally made public, as this contains
-a database password.)
-
-To back up the database, use the tools provided by your service provider
-(if applicable) or the standard mysqldump or pg_dump programs.
-
-For general help on mysqldump:
-http://dev.mysql.com/doc/mysql/en/mysqldump.html
-
-WARNING: If using MySQL 4.1.x, mysqldump's charset conversion may in
-some cases damage data in your wiki. If necessary, set the charset
-option to 'latin1' to avoid the conversion.
-
-For general help on pg_dump:
-http://www.postgresql.org/docs/current/static/app-pgdump.html
-
-
-== Caveats ==
-
-=== Postgres ===
-
-Postgres support is new, and much of the upgrade instructions may
-not apply. The schema was changed significantly from 1.7 to 1.8,
-so you will need to at least use the update.php or web installer,
-as described above.
