Migration from MediaWiki to BlueSpice

< Setup:Installation Guide

Before you start

It is important to check the compatibility of your current MediaWiki installation and the BlueSpice version to which you want to migrate:

  • BlueSpice Version 3.x is based on MediaWiki 1.31.x
  • BlueSpice version 4.x is based on MediaWiki 1.35.x (BlueSpice 4 has not yet been released)

Backup

Create a full backup of your current installation. Commands may differ depending on your operating system.

  1. Create a directory to store the backup:
    mkdir -p /opt/mediawiki-migration-backup/{db,web}

  2. Create the database dump:
    mysqldump -u DB_USER_OR_ROOT -p MEDIAWIKI_DATABASE_NAME > /opt/mediawiki-migration-backup/db/database.sql

  3. Copy everything in the web root to the backup folder:
    cp -Rvf /PATH/TO/MEDIAWIKI/FOLDER/* /opt/mediawiki-migration-backup/web/

We will use this backup later for the migration process as well.

Preparing the migration

You can create a separate user account and database for BlueSpice. This step is optional but recommended. The following steps are based on such a separately created user and database.

If you choose not to create a separate user account and database, replace the following commands accordingly.

  1. Create a MySQL/MariaDB user via MySQL CLI:
    CREATE USER 'bluespice'@'localhost' IDENFITIED BY 'PleaseChooseAComplexPassword';

  2. Create a database for BlueSpice via MySQL CLI:
    CREATE DATABASE bluespice;

  3. Grant the required privileges for the bluespice user to the bluespice database via MySQL CLI:
    GRANT ALL PRIVILEGES ON bluespice.* TO 'bluespice'@'localhost';
FLUSH PRIVILEGES;
    Now we have an empty SQL database and are ready to import.

Importing the data

  1. Import the SQL dump from the backup you created earlier:
    mysql -u bluespice -p bluespice < /opt/mediawiki-migration-backup/db/database.sql
    After this command, enter the password you chose for the bluespice database user.
  2. Next, clean up the old installation folder and create an empty one.
    rm -Rf /PATH/TO/MEDIAWIKI/FOLDER/
    and
    mkdir -p /PATH/TO/MEDIAWIKI/FOLDER/

  3. Next, extract the BlueSpice package and place it into the /PATH/TO/MEDIAWIKI/FOLDER/ 
    cd /PATH/TO/MEDIAWIKI/FOLDER/

  4. Copy the images folder from the backup to the /PATH/TO/MEDIAWIKI/FOLDER/ :
    cp -Rf /opt/mediawiki-migration-backup/images .
  5. Set the correct permissions based on your operating system to the folder /PATH/TO/MEDIAWIKI/FOLDER/ .

Configuration settings

  1. In /PATH/TO/MEDIAWIKI/FOLDER/, create a new file named LocalSettings.php and copy the following content into the file:
      1 <?php
  2 # This file was automatically generated by the MediaWiki 1.35.3
  3 # installer. If you make manual changes, please keep track in case you
  4 # need to recreate them later.
  5 #
  6 # See includes/DefaultSettings.php for all configurable settings
  7 # and their default values, but don't forget to make changes in _this_
  8 # file, not there.
  9 #
 10 # Further documentation for configuration settings may be found at:
 11 # https://www.mediawiki.org/wiki/Manual:Configuration_settings
 12 
 13 # Protect against web entry
 14 if ( !defined( 'MEDIAWIKI' ) ) {

 24 ## The URL base path to the directory containing the wiki;
 25 ## defaults for all runtime URL paths are based off of this.
 26 ## For more information on customizing the URLs
 27 ## (like /w/index.php/Page_title to /wiki/Page_title) please see:
 28 ## https://www.mediawiki.org/wiki/Manual:Short_URL
 29 $wgScriptPath = "/w"; # <--- PLEASE CHECK YOUR DOCUMENTROOT
 30 
 31 ## The protocol and server name to use in fully-qualified URLs

 86 $wgPingback = false;
 87 
 88 ## If you use ImageMagick (or any other shell command) on a
 89 ## Linux server, this will need to be set to the name of an
 90 ## available UTF-8 locale. This should ideally be set to an English
 91 ## language locale so that the behaviour of C library functions will
 92 ## be consistent with typical installations. Use $wgLanguageCode to
 93 ## localise the wiki.
 94 $wgShellLocale = "C.UTF-8";
 95 
 96 ## Set $wgCacheDirectory to a writable directory on the web server

128 # End of automatically generated settings.
129 # Add more configuration options below.
130 
131 
132 # This is the main settings file for all BlueSpice extensions and settings
133 # It will include all files in "$IP/settings.d/" directory

141 
142 # Convenience for debugging
143 # $wgShowSQLErrors = true;
144 # $wgDebugDumpSql  = true;
145 # $wgShowExceptionDetails = true;
146 # $wgShowDBErrorBacktrace = true;
  2. Edit this LocalSettings.php and set the correct values to fit your installation. This current LocalSettings.php might look like different from your MediaWiki installation, because BlueSpice comes with a separate folder for custom settings (settings.d).

Migrating the system

The system is ready to migrate.

  1. Run the following script to start the migration:
    php /PATH/TO/MEDIAWIKI/FOLDER/maintenance/update.php --quick
    Now BlueSpice should be reachable.
  2. Finally execute the following additional scripts:
    php /PATH/TO/MEDIAWIKI/FOLDER/maintenance/rebuildall.php Finally for the search index (ElasticSearch 6.x and ingest-attachment plugins must be installed) php /PATH/TO/MEDIAWIKI/FOLDER/extensions/BlueSpiceExtendedSearch/maintenance/initBackends.php --quick
php /PATH/TO/MEDIAWIKI/FOLDER/extensions/BlueSpiceExtendedSearch/maintenance/rebuildIndex.php --quick
php /PATH/TO/MEDIAWIKI/FOLDER/maintenance/runJobs.php --memory-limit=max

Your migration is complete and your BlueSpice is ready to use!

You can use your old credentials to login.
