This help page describes the upgrade procedure from Semantic MediaWiki 2.5.x to Semantic MediaWiki 3.1.x with native Composer support.

Note that this help page assumes that you use MediaWiki 1.31.0 to 1.33.x. See also the help page on compatibility.
Since SMW 2.5.x is not compatible with 1.31.0 to 1.33.x you must either upgrade to SMW 3.0.x to SMW 3.1.x (preferred).

Step 1 - Backup database and wiki

Backup your wiki database and wiki installation.

Step 2 - Update setup file

Change to the base directory of your wiki1 in your server's shell and modify the "composer.local.json" file to look like this2:

{
	"require": {
                  "mediawiki/semantic-media-wiki": "~3.1.0"
        }
}

Step 3 - Update software

Run the composer command34 from the base directory of your wiki1 in your server's shell to upgrade the source code of Semantic MediaWiki and dependencies:

php composer.phar update --no-dev

Step 4 - Invoke Semantic MediaWiki

Add the following line to the end of your "LocalSettings.php" file:

enableSemantics( 'example.org' );

Note that "example.org" should be replaced by your wiki's domain.

Step 5 - Update database

Run maintenance script "update.php" (MediaWiki.org) from the base directory of your wiki1 in your server's shell to apply the schema changes to your wiki's database:

php maintenance/update.php

Or alternatively use maintenance script "setupStore.php"No description was provided.:

php extensions/SemanticMediaWiki/maintenance/setupStore.php -v

Step 6 - Update database cont.

If you see the upgrade information error message on your wiki's pages run maintenance script "populateHashField.php"No description was provided. from the base directory of your wiki1 in your server's shell to apply further changes to your wiki's database:

php extensions/SemanticMediaWiki/maintenance/populateHashField.php -v

If you do not see the upgrade information error message on your wiki's pages you may skip this step and directly do the next one.

Step 7 - Rebuild data

Run maintenance script "rebuildData.php"No description was provided. from the base directory of your wiki1 in your server's shell to rebuild the semantic data in wiki's database:

php extensions/SemanticMediaWiki/maintenance/rebuildData.php -v --with-maintenance-log

Step 8 - Update configuration

Go to the "Deprecation notices" tab on special page "SemanticMediaWiki"No description was provided. and update your wiki's "LocalSettings.php" file according to the information provided on that page.

If you do not see the "Deprecation notices" tab on on your wiki's special page "SemanticMediaWiki"No description was provided. you may skip this step and you are done.

Some changes to the settings of configuration parameters may require you to rebuild the wiki's semantic data again. This is documented on each configuration parameters documentation page. In this case go back to step 6.

Done!

Semantic MediaWiki and the database use should now be upgraded properly. The wiki may now be used again.

Semantic MediaWiki 3.0.0Released on an unknown date unknown versions of MediaWiki brought deliberate syntax changes which may affect your wiki. Thus have a look at the migration guide for further information.
