Auf Moodle 2.2 aktualisieren

Diese Seite ist noch nicht vollständig übersetzt.

Sie können auf Moodle 2.2. von Moodle 2.1, 2.0 oder 1.9 aktualisieren. Wenn Sie von Moodle 2.0 aktualisieren, lesen Sie bitte auch den Artikel Auf Moodle 2.1 aktualisieren. Wenn Sie von Moodle 1.9 aktualisieren, lesen Sie bitte zusätzlich den Artikel Auf Moodle 2.0 aktualisieren. Danach können Sie direkt auf Moodle 2.2 aktualisieren.

Wenn Sie von einer älteren Moodle-Version aktualisieren, müssen Sie zuerst auf Moodle 1.9.x aktualisieren.

Wir empfehlen, die Aktualisierung zuerst auf einer Kopie Ihrer Moodle-Site durchzuführen und zu testen, bevor Sie Ihre Produktiv-Installation aktualisieren.

Vor der Aktualisierung

NOTE: The upgrade process will irreversibly modify the contents of your database and your moodledata file storage area. If something goes wrong you cannot go back. It is vital that you take good backups of both moodledata and the database in case you have problems with the upgrade. If you are not sure how see Site backup or ask in the moodle.org forums (explaining what your operating system is).

• Read the Moodle 2.2 release notes and check the list of new features
• Check your site to make sure it meets all system requirements for 2.2 in Settings > Site administration > Server > Environment
• Do a full database backup!
• Do a full moodledata backup
• Check your backups carefully
• Remember to purge PHP cache if using any PHP accelerator

Possible issues that may affect you

• If you have custom reports, there have been changes that may require (simple) changes to be made to their code. See the developer documentation dev:General report plugins for details.
• Global search has been removed from core as it was broken. (A new global search is being written for 2.3.)
• Some web service functions have been deprecated. They still work, but check any web service connections you may have to your Moodle for the future.

Checking database schema - old sites

If your Moodle site has been upgraded through many prior versions it is possible that there will be some problems with the database schema (compared to a fresh 2.0 installation). This may cause the upgrade to fail. If your site started life prior to Moodle 2.0 it is a very good idea to check and correct the database schema before upgrading. See Verify Database Schema. You should also run the database integrity checks in the XMLDB editor, see the 'See also' for a link to extra scripts to check for other discrepancies.

Now upgrade

Once you have satisfied the requirements for Moodle 2.2, follow the instructions on the upgrading page.

On Linux servers, Moodle 2.2 supports running the upgrade from the command line, rather than through a web browser. This is likely to be more reliable, particularly for large sites.

After upgrade

The config.php file from your 2.0 installation should work fine but if you take a look at config-dist.php that came with Moodle 2.0 there are more/different options available (e.g. database drivers and settings). It's a good idea to map your old config.php settings to a new one based on the 2.2 config-dist.php.
