Upgrading to Moodle 1.9

Before upgrading, please...

• Check that your site meets all system requirements for 1.9 in Administration > Server > Environment
• Do a full database backup!
• Remember to purge PHP cache if using any PHP accelerator
• Read Upgrading to Moodle 1.8 if you are upgrading to 1.9 from 1.6 or 1.7
• Read Upgrading to Moodle 1.7 if you are upgrading from 1.6

Notes

• If upgrading from 1.6 or later, you must have converted your site to Unicode
• If upgrading from earlier than 1.6, we recommend upgrading to 1.6 first, then 1.8 -> 1.9
• We recommend PHP 5.2 or later, but you must have at least PHP 4.3.0

Now upgrade

Once you have satisfied the requirements for Moodle 1.9, follow the instructions on the upgrading page.

Front page activities

To enable logged-in users to participate in front page activities, such as viewing the site news, the default front page role should be set to student in Administration > Front Page > Front Page settings.

Upgrading more than one version

In general, it is recommended to upgrade via each version of Moodle, for example 1.7 -> 1.8 -> 1.9. An exception to this is when upgrading from 1.5 or 1.6, when it is recommended that 1.7 is skipped, in other words upgrade 1.5 -> 1.6 -> 1.8 -> 1.9. (The main reason for this recommendation is that the default roles settings obtained when upgrading to 1.7 are not ideal for 1.8 onwards.)
