This help page describes the upgrade procedure from Semantic MediaWiki 1.8.x to Semantic MediaWiki 1.9.x with native Composer support.

  • Note that this help page assumes that you use MediaWiki 1.19.0 to 1.23.x. See also the help page on compatibility.
  • Once you have upgraded to Semantic MediaWiki 1.9.x you can continue to upgrade as explained in the relevant help pages.

Step 1 - Backup database and wiki[edit]

Backup your wiki database and wiki installation.

Step 2 - Delete old software[edit]

Delete the directories SemanticMediaWiki/ and Validator/ from the …/extensions/ directory.

Step 3 - Update configuration file[edit]

Remove the formerly required invocations of "Semantic MediaWiki" and "Validator" from the "LocalSettings.php" file, i.e. the following two lines:

require_once "$IP/extensions/Validator/Validator.php";
require_once "$IP/extensions/SemanticMediaWiki/SemanticMediaWiki.php";

Step 3 - Re-install new software[edit]

Re-install Semantic MediaWiki as described on the applicable page.

NoteNote: This involves several steps.


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